0.5 in 10-72. The copper pipe system, which transports water at 70°F, consists of two branches. The pipe for branch ABC has a diameter of 0.5 in. and length of 8 ft, whereas the pipe for branch ADC has a diameter of 1 in. and length of 30 ft. If a pump provides an inlet flow at A of 67.3 gal/min, determine the flow in gal/min through each branch. Take e-80(10-6) ft. The system is in the horizontal plane. Include...

Two large tanks are open to the atmosphere at the top. Water s
pumped from the lower tank to the upper tank through a single PVC
(smooth) pipe. The relationship between Velocity in the pipe (ft/s)
and the pump head (ft) is given. There are no significant minor
losses. What is the flow rate, Q (cfs), in the pipe?

4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...

Question (a) Sulphuric acid is flowing through a pipe (2.5 inch diameter, 50 ft length) in a velocity of 0.006 m2/s. The sulphuric acid has a viscosity of 25 mN.s/m² and density of 1680 kg/m² while the roughness of the pipe surface is 1.3 mm. If the operating temperature is 290K, determine fluid flow (i.e. laminar, turbulent or others). (Given that 1 m= 39.37 inch) (b) Define pump, suction head, impelling head and the total head of a pump. (c)...

3. Water at 10°C is flowing from a lower to an upper pond through a pipe at the rate of 1.0 m/ s. The pipe length is 1000 m and a pump raises the water a vertical distance of 60 m with a head loss of 12.4 m. a) What is the pump head? b) What is the pump power? e What is the pressure increase through the pump?

A 12-in diameter pipe conveys fluid at 8 ft/s between two tanks. The friction factor f is 0.02. The pipe entrance and exits are both squared edged. The pipe also contains a fully-open gate valve. Determine what percent of the head loss is due to minor losses for the following three pipe lengths: (a) 4 ft, (b) 80 ft, (c) 1600 ft. Comment on whether minor losses are always “minor”.

The figure below shows a condenser/cooling tower pipe system needed to remove heat from a water cooled refrigeration condenser and reject the heat to the atmosphere. The amount of heat to be rejected to the atmosphere is 480,000 Btu/hr. The water enters the condenser at 85"F, and the temperature rise of the water through the condenser is 10°F. The total length of the piping in the system is 60 ft. Fittings are as shown. Assume bends to be as shown...

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...

solve both parts a and b please
A centrifugal pump having a head capacity relationship given by the equation; h = 160 - 9.58x10^Q? with hain feet when Q is in gpm, is to be used with a system similar to that shown in Figure 12.14. The fluid is water. Assume the pipe diameter to be 5-in, the total length of constant-diameter pipe is 700 ft, and the friction factor to be equal to 0.022. Neglect all minor losses. For...
