Critical Pressure in Conveyance of Water Formulas

Critical Pressure is the maximum pressure developed in the pipe that will cause it’s buckling in absence of stiffening rings. And is denoted by P_cr. Critical Pressure is usually measured using the Pascal for Pressure. Note that the value of Critical Pressure is always positive. Typically, the value of Critical Pressure is greater than 0.
