Critical External Pressure given Thickness of Pipe Solution

STEP 0: Pre-Calculation Summary

Formula Used

Critical Pressure = (5*Modulus of Elasticity*(Thickness of Pipe)^3)/(3*Diameter of Pipe)
P_cr = (5*E_pa*(t_pipe)^3)/(3*D_pipe)
This formula uses 4 Variables

Variables Used

Critical Pressure - (Measured in Pascal) - Critical Pressure is the maximum pressure developed in the pipe that will cause it's buckling in absence of stiffening rings.
Modulus of Elasticity - (Measured in Pascal) - Modulus of Elasticity is a quantity that measures an object or substance's resistance to being deformed elastically when stress is applied to it in pascal.
Thickness of Pipe - (Measured in Meter) - Thickness of Pipe is the smaller dimension of pipe. It is the distance between the inner and outer or front and back surfaces of the pipe.
Diameter of Pipe - (Measured in Meter) - Diameter of Pipe is the diameter of the pipe in which the liquid is flowing.

STEP 1: Convert Input(s) to Base Unit

Modulus of Elasticity: 1.64 Pascal --> 1.64 Pascal No Conversion Required
Thickness of Pipe: 0.98 Meter --> 0.98 Meter No Conversion Required
Diameter of Pipe: 0.91 Meter --> 0.91 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_cr = (5*E_pa*(t_pipe)^3)/(3*D_pipe) --> (5*1.64*(0.98)^3)/(3*0.91)

Evaluating ... ...

P_cr = 2.82702358974359

STEP 3: Convert Result to Output's Unit

2.82702358974359 Pascal --> No Conversion Required

FINAL ANSWER

2.82702358974359 ≈ 2.827024 Pascal <-- Critical Pressure
