Apropane tank is designed in the shape of a cylinder with two hemispherical ends. the cylinder's height is twice its diameter, and the tank's capacity is 1,000 gal. what is the radius of the tank, to the nearest tenth of a foot?

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
