- Part 1: Do the Analysis of the Ocean Thermal Gradient Power Plant shown below. Your Analysis will be easier to do in EES but it is up to you. Your EES program must be well documented and documentation in your code should reference system sketches. (The cycle and individual components) These sketches are done on attached engineering or typing paper, unless you are able to draw them in EES. You must validate your results with hand calculations on engineering paper that invoke the 1 and 2 Law from the perspective of the entire cycle, not the individual components. Of course, a system sketch is required. nd 1. An ocean thermal gradient power plant using a simple non-ideal Rankine Cycle operates with a peak boiler temperature of 70 °F and a condenser temperature of 40 °F. The warm surface water of the ocean is supplying the thermal energy to the boiler. Assume a high source temperature of 80 °F. The cooler water deeper in the ocean is the sink for heat rejection at the condenser. Assume a…The left side of this equation tells how much energy Q the cylinder gives to the water while it cools. The right side of this equation tells how much energy Q the water and aluminum cup absorb from the cylinder to warm up. Because it is the same energy, they are equal. What is known in this equation? Mcyl 411.7 g, malum 46.5 g, malum+water = 175 g Can you find: mwater =? g Twater = Talum = 20°C (water and cup of room temperature) 90°C, T; = 35°C (hot cylinder and cool "cylinder+cup+water" temperatures) Tcyl kCal Calum = 0.22, Cwater 1 (specific heat of water and aluminum, measured in units kg-°C What are we looking for is Ccul - How we find it? Plug all the numbers into the equation (1), Ccul will be one unknown which you can calculate from the equation. Important, convert all the masses from grams to kilograms! After you find Ccyl, compare it to known value for the copper 0.093(our cylinder is made out of copper). |Ceyl -0.093| % : · 100% 0.093Use the steam tables provided and use 4 decimal places for solving. In an idealRankine cycle, steam first enters the turbine at 10 MPa and 400C. It expands to a pressure of 10 kPa. a.) Draw the proper T-S diagram of the cycle with proper label for the points. b.) Findthe quality of the steam,Qa, Qr, Wt, Wp, Wnet, efficiency, and steam rate

The overall boiler effeciency is 85% with feedwater temperature at 165 degree Centigrade. a) How many kilogram of coal are required per kw-hr if calorific value of coal is 28,000 kJ/kg? b) If coal costs Php 440 per Metric Ton, what is the fuel cost per kw-hr? Copy the problem.Write the simplified ENERGY BALANCE equation for each process based on the givenconditions. Start from the general energy balance form, and arrive at the correct balance byexplaining any addition, deduction, or change in the equation.Use the following as subscripts in your answer: 1 = initial system state; 2 = final system state; i = inletstate, e = exit state.a. A rigid tank transferring heat to its surroundings. b. The seal of an insulated system with a high energy substance is broken, causing the contents tobe evacuated until only 20% of the initial internal energy remained. No heat transfer was detectedin the system’s boundaries. c. Consider a hydroelectric power plant operating in steady conditions, wherein the system consistsof two water reservoirs with a height difference Δz, with a Francis water turbine placed betweenthe stream connecting both.Please provide equations that you are using so I can follow along and learn how to do this. In Jamestown, NY, a coal power plan consumes coal at a rate of 80 tons/hr. When coal burns, it generates approximately 30,000 kJ for every kg of coal burned. The cooling course for the plant is the nearby Chadakoin River nearby and, by code, the power plant cannot reject more than 13.19 x 109 MJ into the river annually. Determine the maximum average power output of this plant and it's maximum thermal efficiency. To check your work, enter the efficiency, as a decimal, in the box provided.
- Write legibly so i can understand 3. The turbine section of a Brayton cycle gas turbine receives hot compressed air at 150 psia and 2100 o R, expands it to 15 psia and develops a gross output of 15,000 HP. Air enters the compressor at 500 R. Determine: d.) thermal efficiency, e) mean effective pressure (psia)A hot water leak in one of the faucets of your apartment can be very wasteful. A continuous leak of one quart per hour (a "slow" leak) at 155 degrees°F causes a loss of 1.81 million Btu per year. Suppose your water is heated with electricity. a. How many pounds of coal delivered to your electric utility does this leak equate to if one pound of coal contains 12,000 Btu and the boiler combustion process and water distribution system have an overall efficiency of 28%? b. If a pound of coal produces 1.81 pounds of CO2 during the combustion process, how much extra carbon dioxide does the leaky faucet produce in a yearWind power is defined as the use of air flow through wind turbines to provide the mechanical force to generate electricity. Wind power is an alternative to burning fossil fuels, and is renewable and produces no greenhouse gas emissions during operation. Modern horizontal-axis wind turbines often use three blades. Theoretically, the maximum power P (unit: watts) that a three-blade wind turbine can extract from the wind power can be calculated as: P = pAv³C₁. . (Equation 1) where p is the air density (kg/m³), A is the sweep area of the turbine (m²) and can be calculated from the length of the turbine blades, and v is the wind speed (m/s). Cp is the power coefficient that is unique to each turbine type. This coefficient represents the amount of kinetic energy from the wind that is captured by the turbine. From the Betz's limit law we know that the best power conversion possible is Cp,max = 0.59. Part 1 Given the following data: Blade length /= 50 m Air density p= 1.5 kg/m³ Power…
- NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A steam power plant receives heat from a furnace at a rate of 280 GJ/h. Heat losses to the surrounding air from the steam as it passes through the pipes and other components are estimated to be about 8 GJ/h. The waste heat is transferred to the cooling water at a rate of 170 GJ/h. Problem 06.017.a - Net power output of steam power plant Determine the net power output. (You must provide an answer before moving to the next part.) The net power output is MW.An engine burns a liter of fuel each 12 minutes …The fuel has specific gravity of 0.8 and a heating value of 45MJ/kg…The engine has an efficiency of 25%...What is the brake horsepower of the engine?In an absorption refrigerator, the energy driving the process is sllPplied not as work, but as heat from a gas flame. (Such refrigerators commonly use propane as fuel, and are used in locations where electricity is unavailable. *) Let us define the following symbols, all taken to be positive by definition: Qf = heat input from flame Qe = heat extracted from inside refrigerator Qr = waste heat expelled to room Tf = temperature of flame Te temperature inside refrigerator Tr = room temperature Use the second law of thermodynamics to derive an upper limit on the COP, in terms of the temperatures Tf, Te, and Tr alone.
