The pressure within a 23.3-m3 tank should not exceed 105 bar. determine the pressure, in bar, within the tank if filled with 1000 kg of water vapor maintained at 480°c using the: (a) ideal gas equation of state. (b) van der waals equation. (c) redlich–kwong equation. (d) steam tables.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
