Question

What is the height difference of the water (density = 1000 Kg/m^3), if the change in velocity is 10 m/s and change in pressure is 500 Pa?

(a) 1.01 m

(b) 5.05 m

(c) 10.1 m

(d) 20.2 m

I have been asked this question during an online interview.

The above asked question is from Mechanical Energy Balance topic in portion 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

Right option is (b) 5.05 m

To explain I would say: ∆h = (500/1000 + 102/2)/10 = 5.05 m.
