Consider a rigid, pressurized stainless-steel (SS-304) propane tank that weighs 18 lbs. (empty) and is initially at thermal equilibrium (Eq.) with its surroundings (1atm, 22°C). The inner dimensions of the propane tank are roughly a cylinder (height: 13¼", diameter: 10¼"). The tank is 99% filled with propane and x=0.05. The welded handle and stand on the tank weighs 1 lbs. (combined) and valve on the tank weighs 1.5 lbs. and has an exit area of 1 cm2 . NOTE: for this problem you will need to look up the thermodynamic properties of propane and SS-304. Show your calculations on the blank pages!
a) List below your references for the properties of propane and SS-304?____________________________________________________________________________ ____________________________________________________________________________
b) What is the wall thickness of the propane tank in mm? _________ mm
c) What is inner volume of the propane tank in mL and gallons? _________ mL _________ gallons
d) What is the pressure inside the tank in psi and kPa? _________ psi_________ kPa
e) What is the mass of liquid propane in the tank in kg and lbs.? _________ kg_________ lbs.
f) What is the volume of gaseous propane in the tank in mL? _________ mL .At t0 = 0 seconds, the valve on the tank is instantly opened until equilibrium (Eq.) is reached @ t = tEq.
g) What is the mass of air (in kg) in the tank @ Eq.? _________ kg
