You are on a factory visit to a plant for food products. Rushing through the factory, you hear that a vapor compression cycle with refrigerant HFC-134a as the working fluid is being used. You see that they use a throttle valve as part of the system and that one part of the cycle is running at 0.32 MPa and another part of the cycle is running at 1.6 MPa. If the compressor is 80% efficient and throttle, condenser, and evaporator...

The Sun delivers roughly 1 kW m−2 of power to the Earth's surface. A parabolic mirror with a 1 m radius is used to focus this energy onto a beaker containing 1 L of water. Estimate the time taken by the mirror to raise the temperature of the water by 50∘C, assuming the specific heat capacity of water to be 4200 J K−1 kg−1 and ignoring energy losses to the surroundings
