Question

Water flows through a horiztonal pipe at a rate of 92 ft³/min. A pressure gauge placed on a 3.3 inch diameter section of the pipe reads 16 psi. What is the gauge pressure in a section of pipe where the diameter is 5.1 inches?

Water moves through a pipe at 5 m/s under an absolute pressure of 330 kPa. The pipe narrows to one half of its original diameter. What is the absolute pressure in the narrow part of the pipe?

Answer 1

this problem is based on Bernoulli's theorem for a horizontal flow.
