6. A spherical balloon is 40 ft in diameter and surrounded by air at 60°F and 29.92in Hg.a. If the balloon is filled with hydrogen at 70 F and atmospheric pressure,what total load can it lift?b. If it contains Helium instead of hydrogen, other conditions remain thesame, what load can it lift?c. Helium is nearly twice as heavy as hydrogen. Does it have half lifting force?Check the gas constant of hydrogen and helium at the back ofThermodynamics 1 by Hipolito Sta Maria. 5. The following expressions relate to a particular gaseous mass: PV = 95T, h = 120+ 0.60T where these units obtain in lb/ft?, V = 500 ft /lb, T in •R and h in BTU/lb.If the specific heats are temperature dependent only, find Cp and Cv.
