Pump efficiency & Flow rate

C.) A water pump has one inlet and two outlets as shown in the attachment. They are all at the same elevation. What pump power is required if the pump is 85% efficient? Neglect all losses. D.) For the pipe enlargement shown, the pressurers at sections 1 and 2 are 46.3 and 49.2 respectively. Determine the weight flow rate (lb/s) of the gasoline in the pipe.

Manometer Problem & Tank Velocity Problem

See Attachment for Problem 75: Figure 6.32 shows a manometer being used to indicate the pressure difference between two points in a pipe system. Calculate the volume flow rate of water in the system if the manometer deflection, h, is 250 mm (Arrangement known as venturi meter). See 2nd attachment for Problem 87

Pipe length?

15%) 3. An angle valve (K = 5.0) is placed in a 50 foot run of 2 " commercial steel pipe. What is the equivalent length of the pipe and valve?

Find total head loss

Find the total head loss if the flow velocity is 16ft/sec in the 2" pipe. The pipes are all commercial steel. (The loss factor for the entrance to the 4" pipe is 0.5 and the 2"pipe exit loss factor is 1.0

Finding Horsepower using the Energy Equation

Please give me some feedback on this problem - In Attachment figure, there are 150 ft of 2" diameter pipe, 90 ft of 6" diam. pipe, and 180 ft of 3" diam. pipe, all wought iron. There are two 90 degree elbows and fully open globe valve. If the exit elevation is zero, what power in horsepower is extracted by the turbine from 20 degrees celcius water when the flow rate is 0.15 ft^3?
