Description
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 andPressure = 1,923 psi
Flow= 32 gpm
1 gallon = 231 cubic inches
1 HP = 550 ft*lb/sec
12 inches =1 ft
Explanation & Answer
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
