The height of a cylindrical tank, containing 15 lb of gas at 70 psia and 115 Farenheit, IS TRIPLE ITS DIAMETER; the gas constant is R = 45 ft lbf/lbm R. find.
a) the tankdiameter in ft.
b)the tank height in ft.
W=15 lbm, P= 70 psia, T=115 F, H=3D, R = 45 ft lbf/lbm°R
Volume of cylireler
1F=459.67R
1ft=12inches
So, T=115F=115+459.67=574.67R
By ideal gas equation
PV=mrt
Unit of bath side is balanced
Diametr D=2.537 ft
Height
H=7.6115ft
