Consider a Carnot-cycle heat pump with R-410a as the working fluid. Heat is rejected from the R410a at 35 oC, during which process the R-410a changes from saturated vapor to saturated liquid. The heat is transferred to the R-410a at 0 oC. The specific volume during the isothermal heat addition process at 0 oC changes from 0.00841 m3 /kg to 0.02994 m3 /kg. a. Show the cycle on P-T, P-v, and T-v diagrams. b. Find the quality at the beginning...

A Carnot heat pump moves heat to a warm house at 24°C at a rate of 300kW. The heat is pumped from the outside air at 7°C. What is the power required by the heat pump? What is the rate of change of entropy for each of the thermal reservoirs (the house, and the outside air)? Does this heat pump satisfy the second law of thermodynamics increase of entropy principle?

A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant changes from saturated vapor to saturated liquid at 40 C in the condenser as it rejects heat. The evaporator pressure is 120 kPa. Determine: (a) the amount of heat absorbed from the refrigerated space; qL = _______________ kJ/kg (b) the net work input; and wnet = ______________ kJ/kg (c) the coefficient of performance of the system. COP = _____________

a. Refrigerators make use of the heat cycles, such as the Carnot cycle, but in order to remove heat from the cold source (fridge) and put that energy into the hot source (the enrivonment), another energy source must be added to the system to make this occur. The minimum energy to be supplied follows the equation given below. Find an expression for the coefficient of performance in terms of Th and Tc. coefficient of performance (c) = heat...

A Carnot-cycle refrigerator rejects heat at the pressure of 1000 kPa during which the working fluid R -134a changes from saturated vapor to saturated liquid. The heat is added to the cycle at the pressure of 320 kPa. Show the cycle in a T-s diagram and determine the coefficient of performance of the cycle using a) the first law of thermodynamics b) the Carnot cycle efficiency equation and c) the T-s diagram.

Describe the different components of GDP by using the Circular Flow Model. In your description be sure to note how the different components interact in the Product, Resource, and Financial Markets. Why do we get the same number when we count the total output and when we count total income? What would cause one of these components of GDP to decrease? Why would a decrease in one of these components typically lead to a decrease in other components? Why did...
