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.    

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
