7. Total pressure, total efficiency, static efficiency
Total Pressure: eqn. 5.1, pg 127
Find v: eqn. 5.2
Conversions:
1 “H2O = 249 Pa
1 ft/min = m/sec
1 lb/in^3 = kg/m^3
1 ft^3/min = m^3/sec
1 HP = Watts
Total efficiency eqn. 5.3
Static efficiency eqn. 5.4
Assume 1750 rpm
Outlet of 10” x 12”
Q = cfm
Static pressure = 2”
50 hp
Density = 3.9E-5 lb/in^3
