Question

1 point
In a thermal power plant work
done by the steam turbine is
900 J/kg. The work consumed
by the pump is 50 J/kg. Find
Net workdone
750 J/kg
O 850 J/kg
580 J/kg
O 570 J/kg​

Answer 1

Explanation:

Determine (a) the net work per unit mass of steam flow in kJ/kg, (b) the heat transfer to the steam passing through the boiler in kJ/kg, (c) the ...

Answer 2

850J/kg(ans)

It is given in the problem that

The thermal power plant work done by the steam turbine is 900J/kg.

It is also given that some work is being consumed by the pump.

The work or energy which gets consumed by the pump is 50J/kg.

Then the network done by the thermal plant will be

work done by the plant -work consumed by the pump=(900-50)=850J/kg.(ans)
