Consider a balloon contains initially 40 liter of Helium at 105 kPa and 20 oC, The balloon is connected to a supply line of helium through a valve that is opened allowing helium to further fill the balloon to 150 kPa such that pressure in the balloon is expressed as: P = 750 V 0.5 – 45, Where P is in kPa and V is m3 . Considering Helium as ideal gas: a- Find the mass of Helium entered the balloon if the process is isothermal. b- Find the work done during the process.
