Analyzing Internally Reversible Flow ProcessesA 3-hp pump
Chapter 6, Problem 181P(choose chapter or problem)
A 3-hp pump operating at steady state draws in liquid water at 1 atm, \(60^{\circ} \mathrm{F}\) and delivers it at 5 atm at an elevation 20 ft above the inlet. There is no significant change in velocity between the inlet and exit, and the local acceleration of gravity is \(32.2 \mathrm{\ ft} / \mathrm{s}^{2}\). Would it be possible to pump 1000 gal in 10 min or less? Explain.

QUESTION:
A 3-hp pump operating at steady state draws in liquid water at 1 atm, \(60^{\circ} \mathrm{F}\) and delivers it at 5 atm at an elevation 20 ft above the inlet. There is no significant change in velocity between the inlet and exit, and the local acceleration of gravity is \(32.2 \mathrm{\ ft} / \mathrm{s}^{2}\). Would it be possible to pump 1000 gal in 10 min or less? Explain.
ANSWER:Step 1 of 1
We have to find the possibility of a 3-hp pump operating at steady state to pump liquid water of 1000 gal in 10 min or less.
To pump 1000 gal of water in 10 min or less would require a volumetric flow rate of
0.006316 m3 /s
The corresponding mass flow rate is
Where,
specific volume of liquid water at (From Table A-3)
60 oF = 1.0009m3/ kg
So,
