Calculate the fluid horsepower to 2 decimal points for the situation given below. The formula for fluid power from a 100% efficient motor is: 

Power = Pressure * Flow and 
Pressure = 1,923 psi 
Flow= 32 gpm 
1 gallon = 231 cubic inches 
1 HP = 550 ft*lb/sec 
12 inches =1 ft

Thank you for the opportunity to help you with your question!

PRESSURE = 1923 PSI = 1923lb/1inch square =  1923 *24lb/ft = 46152lb/ft^2

FLOW= 32GPM = 32/60 GPS = 32*231/60 CM3/S = 123.2CM3/S 

BUT 1728 INCHES CUBED = 1ft^3 =  0.071296 ft^3/s

HP = 46152lb/ft^2 * 0.071296 ft^3/s =3290.45 ft*lb/sec

1 HP =550 ft*lb/sec 

3290.45 FT*LB/SEC

= 3290.45/550 = 5.98 HP

Please let me know if you need any clarification. I'm always happy to answer your questions.
