R 134a flows at steady state through a horizontal pipe havingan inside diameter of 4 cm, entering as saturated vapor at -8degrees C with a mass flow rate of 17 kg/'min. Refrigerant vaporexits at a pressure of 2 bar. If the heat transfer rate to therefigerant is 3.41 kW, determine the exit temperature, in degreesC, and the velocities at the inlet and exit, each in m/s.
If a 2-mm diameter pellet is illuminated from the left and the right by laser beams, such with a diameter of 1 cm and a power of 1 megawatt, estime the pressure applied to the pellet, assume all the light that hits the pellet is absorbed.
