Question

through the cracks. Determine the re house due to mass as a result of u water pump increases the water pressure from psia. Determine the flow work, in Btu/lbm, Answer: 0.945 kw transfer. 6I8E A war 15 psia to 80 required by the pump f a refrig- 6-19 Refrigerant-134a enters the compressor o eration system as saturated vapor at 0.14 MPa and leaves as superheated vapor at 0.8 MPa and 60°C at a rate of 0.06 kg/s. Determine the rates of energy transfers by mass into and out of the compressor. Assume the kinetic and potential energies to be negligible. th 12 (a 6-20E Steam is leaving a pressure cooker whose oper- ating pressure is 20 psia. It is observed that the amount of a liquid in the cooker has decreased by 0.6 gal in 45 minutes 6 after the steady operating conditions are established, and the ve cross-sectional area of the exit opening is 0.15 in2. Deter- lo mine (a) the mass flow rate of the steam and the exit velocity, d (b) the total and flow energies of the steam per unit mass, and (c) the rate at which energy is leaving the cooker by steam. at Steady-Flow Energy Balance: Nozzles and Diffusers 6-21C A diffuser is an adiabatic device that decreases the kinetic energy of the fluid by slowing it down. What happens to this lost kinetic energy? 6-22c The kinetic energy of a fluid increases as it is acceler- ated in an adiabatic nozzle. Where does this energy come from? 6-23C Is heat transfer to or from the fluid desirable as it flows through a nozzle? How will heat transfer affect th fluid velocity at the nozzle exit? 6-24E Air enters a nozzle steadily at s0 and 150 fus and leaves at 14.7 psia aO F and 900 fuls. The st

Explanation / Answer

22 C. The kinetic energy of a fluid increases as it is accelerated in a adiabatic nozzle because as nozzle is a device which increases the velocity of fluid at the cost of pressure and in this manner it converts the internal energy(i.e. pressure energy) of fluid into the kinetic energy
