The house is heated with electricity at a cost of $0.10kWh Calculate the RSI-total for the walls using the tabular method demonstrated in class, and the temperature drop through each element for the January 2.5% temperature. Calculate the rate of heat flow through the wall again for the January 2.5% temperature. Plot the temperature profile approximately to scale through a vertical cross-section of the wall. Calculate the January heating cost for the building. Calculate the annual heating cost for the building. Now add 2" ( 50.8mm ) of extruded polystyrene, smooth skin surface, 35kgm3 rigid insulation to the inside surfaces…A conditioned space has a calculated heat loss at the design maximum heating day of 10,000 BTUs / Hr to maintain an interior temperature of 70 F. We will use a hydronic baseboard style convector to heat the space. The style we have chosen comes in standard lengths. At rated temperature and flow of hydronic heating fluid for each 1 foot of length the heater will add 750 BTUs /Hr to the room. What length of heater can just maintain the temperature on the worst day? For this example we are ignoring other sources of heat loss such as ventilation or drafts.The schematic below illustrates a tank formed from two zones, i.e. liquid and solid. The tank is heated from the left-side with a time-varying solar heat radiation g,ol =f(t) (Wim), while the right-side is kept at a low temperature T. The top surface of the tank is subjected to the ambient conditions, i.e. (hair & Tair ), while its bottom is thermally insulated. Conjugate heat transfer takes place between the two-physically different zones through the fluid-solid interface separating them, while fluid flow is induced due to buoyancy effects where the buoyancy force is approximated according to Boussinesq formulation Fiuoyaney=P0 Bg(T-To). Explain the following: 1- The assumptions required to simulate the below problem. 2- The conservation equations governing the transport phenomena in each zone. 3- The boundary conditions closing the mathematical model. 4- The discretized form of each conservation equation stated in (point 2) above. 5- The appropriate differencing scheme to be used for…
- a/2 It is generally known fact that heat loss occurs from the building/facility through walls and roofs and not through the ground. We have to design a heated hangar-shaped warehouse for IT components with an arched roof with the actual volume of two and a half thousand cubic meters. Taking into account the great importance of upcoming Global Green Turn, we have to design such a hangar which exterior surface - the sum of the surfaces of the two end walls and the surface of arched roof - would be the smallest possible. a Task: How many meters would be the length, width and height of such a hangar that would satisfy the above condition? 3:54:01The operators have noticed that the performance of the reactor is somewhat different to thedesign specifications and suspect that the thermal cycling may be responsible. The seniorprocess engineer would like you to analyse two periods:- The period when the reactor is initially heated up and held at the operating temperature.- The period after the reactor is taken offline for maintenance and then heated up again.You should consider the effect of the tube expansion on the operating variables and theoverall effect on pressure drop and conversion. Compare these responses to the estimatedperformance according to the design basis.You may include any equations or diagrams that you consider necessary to support yourdiscussion.
