3. The design of a pump and pipe system has been completed, except for the valves. The system
is used to transpor10t water at 120°F through 2 nom sch 40 commercial steel pipe at a required
flow rate of 85 gpm. Without the valves, the pump selected has the capability to overcome an
additional 18 psi of pressure drop due to the valves and still provide the required flow rate. The
pipe/valve joints are threaded. Determine how many 2-inch globe valves can be installed in this
pump and pipe system.
4. Figure 1 shows a pump and pipe network being used to transport heptane at 120°F to a large,
elevated, closed storage tank. The tank is pressurized and maintained at 18 psia. The volumetric
flow rate of the heptane is 500 gpm.
a. Specify the nominal diameter of the check valve.
b. Determine the pump discharge pressure required (psia) to move the heptane
through the discharge pipe.

- 1. Steam leaves the boiler of a power plant at 5 MPa, 500°C as shown in the following figure. As the steam passes to the turbine, the temperature drops to 496°C before it enters the turbine due to a heat loss through the pipe's insulation. The pressure drop in the pipe connecting the boiler to the turbine is negligible. The steam then passes through an adiabatic turbine and exits at 10 kPa. The turbine has an isentropic efficiency of 85% and is delivering 1000 MW of power. Determine the following.
