Description	<div style="color: rgb(68, 68, 68); font-family: Consolas; font-size: 15px;"><div>Equation for mean pressure for steady flow in a gas pipe at pressures below 1000 psia and temperatures above 60°F, the change in compressibility factor z with Pressure is approximately linear. Therefore, the compressibility factor z can be expressed as a constant, so the average pressure of the gas fluid can be calculated as follows.</div><div><br><b>Pm = 2/3 * (P1^3 - P2^3)/(P1^2 - P2^2)</b></div><div><b><br></b><span style="color: rgb(43, 0, 254);">def pmean(p1, p2):</span></div><div><span style="color: rgb(43, 0, 254);"><br></span><span style="color: rgb(43, 0, 254);">    return 2/3*(pow(p1, 3) - pow(p2, 3))/( pow(p1, 2) - pow(p2, 2))</span></div><p><span style="color: rgb(43, 0, 254);"><br>print("Gas mean pressure of 120 psia and 100 psia = ", pmean(120, 100))</span></p><p>When run the code, you will receive the following results.</p><p><span style="color: rgb(43, 0, 254);">Gas mean pressure of 120 psia and 100 psia =  111.429</span></p><div><br></div></div>
