Answer to Question #260303 in Chemical Engineering for Leke

Question

Calculate the pressure gradient in psi/ft from mud weight of 10.0ppg b. Calculate the pressure gradient in psi/ft from mud weight of 80Ib/ft^3.

Answer 1

psi/ft = mud weight, ppg x 0.052

10.0 ppg fluid psi/ft = 10.0 ppg x 0.052 psi/ft = 0.52. 

Pressure gradient, psi/ft, using mud weight, lb/ft 3. psi/ft = mud weight, lb/ft^3 x 0.006944

80 lb/ft³ fluid psi/ft = 80 lb/ft³ x 0.006944

psi/ft = 0.5555
