Question

What are the total degrees of freedom if the number of species are 4, total streams are 2, stream temperature 2, stream pressure 1 and heat released 1, extent of reaction 1?

(a) 4

(b) 7

(c) 11

(d) 15

This question was posed to me during an online exam.

I want to ask this question from Degrees of Freedom Analysis topic in chapter Energy Balances that Include the Effects of Chemical Reaction, Ideal Processes, Efficiency and the Mechanical Energy Balance and Heats of Solution and Mixing of Basic Chemical Engineering

Answer 1

Correct choice is (c) 11

For explanation: Degrees of freedom = 4 + 2 + 2 + 1 + 1 + 1 = 11.
