Question

What is the height difference of the water (density = 1000 Kg/m^3), if the change in velocity is 6 m/s and change in pressure is 2000 Pa?

(a) 1.2

(b) 2.0

(c) 3.6

(d) 4.4

This question was addressed to me in my homework.

This key question is from Mechanical Energy Balance topic in section 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

The correct option is (b) 2.0

Best explanation: ∆h = (2000/1000 + 6^2/2)/10 = 2.0 m.
