Nitrogen enters a steady-flow heat exchanger at 150 kPa, 10°C, and 116 m/s, and it receives heat in the amount of 120 kJ/kg as it flows through it. Nitrogen leaves the heat exchanger at 100 k.

What is the initial pressure, temperature, and velocity of nitrogen as it enters the steady-flow heat exchanger?

Options:
A) 150 kPa, 10°C, 116 m/s
B) 150 kPa, 10°C
C) 10°C, 116 m/s
D) 116 m/s

Answer :

Final answer:

The initial conditions of nitrogen as it enters the heat exchanger are 150kPa, 10°C, and 116m/s, making Option A the correct choice.

Explanation:

The initial conditions of nitrogen as it enters the steady-flow heat exchanger are provided in the question. These conditions include the pressure, temperature, and velocity of nitrogen. Specifically, nitrogen enters the heat exchanger at a pressure of 150kPa, a temperature of 10°C, and a velocity of 116 meters per second (m/s). Therefore, the correct option that describes the initial pressure, temperature, and velocity of nitrogen as it enters the steady-flow heat exchanger is Option A: 150kPa, 10°C, 116(m)/s.
