Answer to Question #280239 in Molecular Physics | Thermodynamics for CHUKSIE

Question

The height of a cylindrical tank, containing 20 lb of gas at 70 psia and 115 Farenheit, IS TRIPLE ITS DIAMETER; the gas constant is R = 45 ft lbf/lbm R. find.

Answer 1

Solution:

$V=\frac{mRT}p,$

$V=Sh=\frac{\pi d^2}4 h=\frac{\pi h^3}{36},$

$h=\sqrt[3]{\frac{36 mRT}{\pi p}}=8.02~ft.$
