Hi, using the SSSF equation for this problem:

A large steam turbine operates with a steam flow rate of 72,000 kg/hr. The conditions

at the inlet and outlet are shown in the table below. Determine the power produced by

the turbine

a. If heat losses are negligible, and

b. If heat losses are equal to 50,000 KJ/hr.

Inlet Conditions / Exit Conditions

Pressure inlet 1 MPa - outlet - 0.1 MPa

Temperature inlet 540°C - outlet - 69°C

Velocity inlet 40 m/s - outlet 130 m/s

Elevation above reference plane 3 m - outlet 0 m

Enthalpy ( kJ/kg) inlet 3505.4 - outlet 2189.3

g=9.81m/s2

I got

a) = 26169.58 kW

b) = 26155.69 kW

Am I way off, or is that correct?

Thanks in advance.

I am also getting exactly same answers for both a and b. :)

Of course, yes, thanks. :)
