Question

Water at 100^{o}F flows from one tank to another through
two pipes A (D=3") & B (D=6") running in parallel between the
same two tanks through the same drop in elevation (25 ft). The
lengths of the 3” and 6” new, asphalt-dipped cast iron pipe (ϵ =
0.0004 ft) are 100 ft. Use ν=7.4 x 10^{-6}
ft^{2}/s. Determine the flow in cfs . Ignoring
*minor* losses ...**determine Q _{A} and
Q_{B}**.

Answer #1

thank you

A pump is used to carry water (T =60 oF and ν = 1.217×10-5
ft2/s) from a large tank (elevation of surface = 30 ft and at
atmospheric pressure) through a pipe to the exit (elevation 60 ft)
at a rate Q = 1.5 cfs as shown below. The pipe is made of cast iron
(ε = 0.00085 ft). The pipe segment before the pump has length L =
500 ft (three horizontal sections of 160 ft each and two...

Water flows through two horizontal pipes that are connected one
after another but located at different heights. There are pressure
gauges on each of the pipes. The speed of the water through the
lower pipe is 5.0 m/s. The two pipes have different diameters. The
lower pipe has a diameter of 6 cm and the higher one 4 cm. Assume
no viscous losses.
a. Draw a diagram of the situation and calculate the speed in
the upper pipe.
b. What...
