A piston/cylinder setup contains 1 kg of air at 20°C with an initial volume of V1=0.1 m3, as shown in Fig. Q7. Initially, the piston rests on some stops, but it is possible for it to move within the cylinder without friction. To lift the piston and start such motion, an air pressure of 1400 kPa is required. Now, heat is transferred to the system so that the temperature of the air reaches to a final value of 300°C. Fig. Q7 A. Which statement is true? The air can lift the piston before the temperature reaches to 300°C The air cannot lift the piston before the temperature reaches to 300°C
Q2: A nozzle is a device for increasing the velocity of a steadily flowing fluid. At the inlet to a certain nozzle the specific enthalpy of the fluid is 3025 kJ/kg, the inlet area is 0.1 m and the specific volume is 0.19m'/kg. At the exit from the nozzle the specific enthalpy is 2790 kJ/kg, the area is 0.023 m and the specific volume is 0.5 m'/kg. The nozzle is horizontal and there is a negligible heat loss from it. Calculate: i) The velocity of the fluid at the inlet and exist; ii) The rate of flow of fluid

A hot benzene vapor stream at 500oC and 1 bar is rapidly cooled by mixing with liquid benzene at 25oC and 1 bar. The stream leaving the mixer must be 200oC and 1 bar. Assume the reactor is at constant volume. Determine the flow rate (in mol/hr) of the liquid benzene feed stream assuming the flow rate of the hot benzene vapor stream is fixed at a certain value x (specified in the quiz question). Use the polynomial approximations for heat capacity and Table B.20 when appropriate. Assume the flow rate of the hot benzene vapor stream is fixed at 1,253 mol/hr and the liquid benzene feed stream is your reference state. What flow rate (mol/hr) of the liquid benzene feed stream must be used? Round your answer to the nearest tenth and do not include units. Use Tables B.17 and B.20 to tabulate relevant data. Remember that temperatures for polynomial heat capacities are in Kelvin.
