ENGR5003 Lecture 4, slide 7 (Q1 - Steady Flow Energy Equation)

A steady-flow device operates at steady state. Which statement best describes the Steady Flow Energy Equation?

Formulas you may need

SFEE: $\dot Q - \dot W = \dot m\left[(h_2 - h_1) + \tfrac12(C_2^2 - C_1^2) + g(Z_2 - Z_1)\right]$ (on the formula sheet)

AEnergy can only be transferred as heatBEnergy entering the control volume must equal energy leaving itCThe temperature of the fluid must remain constantDThe pressure of the fluid must remain constant
