Arigid tank with a volume of 1.8 m3 contains 32.9333 kg of saturated liquid–vapor mixture of water at 90°c. now the water is slowly heated. determine the temperature at which the liquid in the tank is completely vaporized. use data from the steam tables.

245°C

Explanation:

Properties of steam at 90°C

to find dryness fraction

v is the specific volume,

0.0546=0.001035+x(2.39-0.001035)

x=0.0224

When all water will covert in vapor steam then

volume

Now from steal table we can say that temperature corresponding to vapor volume is 245°C.

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.
