Amass of 5 kg of saturated water vapor at 150 kpa is heated at constant pressure until the temperature reaches 200°c. calculate the work done by the steam during this process.

The work done by the steam is 213 kJ.

Explanation:

Given that,

Mass = 5 kg

Pressure = 150 kPa

Temperature = 200°C

We need to calculate the specific volume

Using formula of work done

Where,R = gas constant

T = temperature

P = pressure

=Atmosphere pressure

m = mass

Put the value into the formula

Hence, The work done by the steam is 213 kJ.
