Question

Water vapor at 10 MPa 700°C enters a turbine operating at steady state with a volumetric flow rate of 0.36 m^3/s.

a. True
b. False

Answer 1

The statement is false because at 10 MPa and 700°C, water is in the supercritical region and cannot enter a turbine.

Step-by-step explanation:

The question is asking whether the statement is true or false: Water vapor at 10 MPa 700°C enters a turbine operating at steady state with a volumetric flow rate of 0.36 m^3/s.

To answer this, we need to understand the conditions in which water changes phase from vapor to liquid. At 10 MPa and 700°C, water is in the supercritical region, where it exists as neither a liquid nor a gas. Therefore, it cannot enter a turbine in this state.

Therefore, the correct answer is: b. False
