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.

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.
