A facility that receives water at an elevation of 350 ft at the water meter is 4.1 miles from the water tower. The water level in the tower is 527 ft. The water flow rate is 110 gpm. Assume an 8-in. ductile or cast iron pipe with flanged fittings. The supply line includes the following fittings: 2 90-degree elbows

2 gate valves

17 line flow tees

6 branch flow tees

1 swing check valve

Find the total dynamic head and actual water pressure at the water meter of this facility.

What is the static head at a sink on the second floor if the sink faucet elevation is 14 feet above the meter elevation? Hint: Static head depends only on elevation.

The water supply line from the meter to the house and up to the second floor sink is a 1-inch copper pipe with screwed fittings. If the pipe from the meter to the second floor is a total of 75 feet long and includes four line flow tees, a swing check valve and seven regular 90-degree elbows, calculate the actual pressure at the sink. Assume a flow rate of 10 gpm.

Hint: the actual pressure at the sink is affected by the head loss from the water tower to the sink (which included head loss from the tower to the meter and from the meter to the sink).

please please help
