An accumulator is to be sized to supplement pump delivery during peak demand with 10 liters of fluid between the pressures of 14 MPa and 10 MPa. To be sure that fluid is available from the accumulator at 10 MPa, it is precharged to 8 MPa. What size should the accumulator be if atmospheric pressure equals 101 kPa and the process is consid- ered to be isothermal?

Q . It is proposed to pump 8,000 kg/h of toluene at 114 oC and 1.1 atm abs pressure from the reboilerof a distillation tower to a second distillation unit without cooling the toluene before it enters thepump. If the friction loss in the line between the reboiler and pump is 7 kN/m2 and the density oftoluene is 866 kg/m3 . How far above the pump must the liquid level in the reboiler be maintained togive a net positive suction head of 3.5 m? Calculate the power required to drive the pump if the pumpis to elevate the toluene 10 m. The pressure in the second unit is atmospheric and the friction loss inthe discharge line is 35 kN/m2 . The velocity in the pump discharge line is 4 m/s.

1.) A hand pump is used to inflate a bicycle tire to a gauge pressure of 70 psi. a) How much work must be done if each stroke of the pump is an adiabatic process and what is the final temperature of the gas? b) We inflate the tire in two steps: (i) an isobaric compression and (ii) an isochoric increase in temperature.
