Question

What are the assumptions used for deriving the first law for Steady State Steady Flow
(SSSF) process?

Answer 1

Answer:

Explanation:

The fluid flows through a machine or piece of apparatus is constant. This type of flow is called steady flow.

✴Assumptions are:-

The following assumptionsare made in the system analysis:-

[1] The mass flow through the system remains constant.

[2] Fluid is uniform in composition.

[3] The only interaction between the system and surroundings are work and heat.

[4] The state of fluid at any point remains constant with time.

[5] In the analysis only potential, kinetic and flow energies are considered.
