Concept explainers

Temperature Difference and Heat Transfer

Whenever there is a flow of heat flux resulting from a temperature gradient within the material or between two materials, there is heat transfer. Heat transfer primarily arises due to temperature differences between two bodies or within bodies. The term temperature gradient denotes temperature differences or variation of temperature due to change in some quantity. The fundamental use of the concept of temperature is found in the zeroth law of thermodynamics.

Consider the thermal system shown below. The temperature of the inflow liquid is kept constant, and the liquid inflow rate G kg/s is also kept constant. For t <0 the system is at steady state, wherein the heat input from the heater is U kcal/s and the temperature of the liquid in tank 2 is 0,°C. At t 0 the heat input is changed from U to U + u where u is small. This change will cause the temperature of the liquid in tank 2 to change from 02 to 02 +82. Taking the change in the heat input from the heater to be the input to the system and the change in the temperature of the liquid in tank 2 to be the output, obtain the transfer function 02(s)/U(s). Assume that the thermal capacitances of tanks 1 and 2 are Ci kcal/°C and C2 kcal/C, respectively, and that the specific heat of the liquid is c kcal/kg°C. The steady-state heat flow rates from tanks 1 and 2 are the same, Q kcal/s. The changes in and heat flow rates from tanks 1 and 2 are q2, respectively. U +u G Tank 1 O+ 0, O+ 0, O+ 42 Tank 2

A vapor compression refrigeration cycle uses steam as the working fluid. Steamflows steadily with a mass ow rate of 0.5 kg/s. Saturated vapor at 2.0 o C (State 1) enters an uninsulated compressor and it is compressed to 0.35 bar (State 2). Heat transfer at the rate of 105 kJ/s occurs from the compressor to its surroundings and the heat transfer exactly balances the entropy generation rate so that s2 = s1. The boundary and surrounding temperature of the compressor is measured to be 26.67 o C. Steam exits as saturated liquid at 0.34 bar (State 3) from the condenser. Steam leaving the condenser is then throttled in an expansion valve (State 4) before entering a constant pressure evaporator to complete the thermodynamic cycle. (a) Calculate the power (kJ/s) for the compressor. (b) Determine the isentropic efficiency (%) of the compressor. (c) Calculate the entropy generation for the compressor. (d) Find the coefficient of performance of the refrigeration cycle. (e) Show the cycle on T-s…
