The total length of the piping system made of cast iron providing hot water to a house is considered to have a 42m length with a constant diameter. The entrance gage pressure is 85 kPa and exit at 15 kPa gaged. Consider the water density equal 980 Kg/m' and the viscosity 1.138x10 Kg/ms. a) Compute the piping system diameter if the volumetric flow rate provided by this system is equal to 0.1 L/s. There is no pump present in this...
1/9 1 Piping system (14 points) Water is pumped from a reservoir to a large receiver vessel which is maintained at p4 6 bar (absolute) through the operation of the pump and a high pressure nitrogen supply that bleeds into the tank through a regulator. The water enters through an opening at the top of the vessel. A drain is provided at the low point in the system. Elevations are as shown. All valves are gate valves (k = 0.15)...

A pump transports water from Tank 1 to Tank 2 through a constant-diameter piping system as shown below (not to scale). The flow rate is controlled by two gate valves, the gate valve I controls the main pipeline, while the gate valve II controls the loop line from T-joint A to T-joint B. All pipes are galvanized steel pipe of diameter D = 4 in. It has a total length of Li2= 620 ft from tank 1 to tank 2....
