Problem 143HP

Steam at 3 MPa, 400°C enters a turbine with a volume flow rate of 5 m3/s. An extraction of 15% of the inlet mass flow rate exits at 600 kPa and 200°C. The rest exits the turbine at 20 kPa with a quality of 90% and a velocity of 20 m/s. Determine the volume flow rate of the extraction flow and the total turbine work.

Problem 143HP

Steam at 3 MPa, 400°C enters a turbine with a volume flow rate of 5 m3/s. An extraction of 15% of the inlet mass flow rate exits at 600 kPa and 200°C. The rest exits the turbine at 20 kPa with a quality of 90% and a velocity of 20 m/s. Determine the volume flow rate of the extraction flow and the total turbine work.

ANSWER:

Solution 143 HP:

Step 1 of 2:-

The steam that is entering has a pressure of 3 MPa.

The temperature is, .

The volume flow rate is,

The extraction of the inlet mass which exists at at 600 kPa is a5%.
