Question

What is the height difference of the water (density = 1000 Kg/m^3), if the change in velocity is 2 m/s and change in pressure is 100 Pa?

(a) 0.21 m

(b) 0.42 m

(c) 0.56 m

(d) 0.84 m

I got this question in examination.

My question comes from Mechanical Energy Balance topic in division 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 choice is (a) 0.21 m

To elaborate: ∆h = (100/1000 + 2^2/2)/10 = 0.21 m.
