inch diameter at a velocity of 6 ft/s. Is this flow laminar
or turbulent?

b. Calculate the diameter of the pipe at suction side if the velocity of air flow is 22.82 m/s with flow rate of 2.96 m³ /second.
c. Compute the velocity head at suction side if the velocity is 33.68 m/sec.
8. In the regenerative circuit shown below, the pump's flow rate is 10 gpm. If the piston diameter is 7 in
and the rod diameter is 5 in (not a 2:1 cylinder), calculate the extension speed in in/min. Also calculate
the oil flow rate at points A and B in gpm. (recall 1 gal = 231 in')
