In large buildings, hot water in a water tank is circulated through a loop so that the user doesn’t have to wait for all the water in long piping to drain before hot water starts coming out. A certain recirculating loop involves 40-m-long, 1.2-cm-diameter plastic (smooth) pipes with six 90° threaded smooth bends and two fully open gate valves. If the average flow velocity through the loop is 2.5 m/s, determine the required power input for the recirculating pump. Take the average water temperature to be 60°C and the efficiency of the pump to be 15 percent. The required power input for the recirculating pump =

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...

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....

A farmer is to pump water at 70'F from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plastic pipe with three flanged 90 smooth bends. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the river normal to the flow direction of water to take advantage of the dynamic pressure. The elevation difference between the river and the free surface of the tank is 12 ft. For a...

A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere through a 100-m-long pipe. The friction coefficient of the pipe is taken to be 0.015 and the effect of the kinetic energy correction factor can be neglected. In order to drain the tank faster, a pump is installed near the tank exit. Water tank Pump Required...

1. Water is pumped from a low reservoir to a high reservoir that is 20 m higher in elevation. The water is flowing at 1.5 m/s through a 305 mm internal diameter piping system. The water is at 18 degrees C. There are 1,000 m of piping, six standard 45 degree bends, two standard 90 degree bends, a branch flow tee, three gate valves, a swing check valve, a square inlet and a square outlet. The piping and valves are...
