The height of a cylindrical tank, containing 20 lb of gas at 70 psi and 115 Farenheit, IS TRIPLE ITS DIAMETER; the gas constant is R = 45 ft lbf/lbm R. Find the tank's dimensions in feet
No idea now on the pressure stuff and all those nonmetrics bring back bad memory's. But I there is a formula for volume of cylinders and you can replace the height by 3xradius
