Problem 5.5.15^∗

Statement

5.5.15^∗. A factory chimney $50 \,m$ high carries away smoke at a temperature of $60 \,^{\circ}C$ . Determine the pressure difference in the chimney that provides the draft. The air temperature is $−10 \,^{\circ}C$ ; the air density is $1.29 \,kg/m^3$

Solution

Answer

$\Delta P = 137 \,Pa$
