OIL PRESSURE DROP (PSI) CODE

PERFORMANCE CALCULATION

D = 4 PSI E = 5 PSI F = 10 PSI

A = 1 PSI B = 2 PSI C = 3 PSI

J = 30 PSI K = 35 PSI L = 40 PSI

G = 15 PSI H = 20 PSI I = 25 PSI

F s =

Horsepower to be removed (HP) x 2545 x Cv °F (Oil Leaving  - Ambient Air Entering)

BTU hr °F =

 Represents desired fluid leaving the cooler.

Note: When a model selection has been made, record whether the selection was from the one pass curve or the Two Pass curve so that the unit can be properly plumbed. Incorrect installation can seriously affect the performance.

note: AIHTI reserves the right to make reasonable design changes without notice.
