Choke Nipple Information

Gas volume is sometimes determined by flowing through a choke nipple. The formula used is:
CP
Q =
√GT

Q = Flow rate, Mcf per day at 14.4 psia and 60°F.

C = Coefficient

P = Upstream pressure, psia (gauge reading plus 14.7)

G = Specific Gravity of Gas (Air = 1.00)

T = Upstream Temperature of Gas, °R (°F plus 460)

If specific gravity and temperature are unknown, an approximation can be obtained for field estimates
by using a specific gravity of 0.60 and a temperature of 540°R (80°F + 460). Under these conditions,
the formula becomes:
CP
