Question

15 Kg/s of a fluid with density 5 Kg/m^3 is passed into a tank of capacity 30 m^3, how much time will it take to fill the tank?

(a) 3 Second

(b) 10 Second

(c) 30 Second

(d) 100 Second

I had been asked this question in an internship interview.

This is a very interesting question from Flow Rate topic in division Moles, Density & Concentration of Basic Chemical Engineering

Answer 1

Right choice is (b) 10 Second

To explain I would say: Flow rate of fluid = 15/5 = 3 m^3/s, => Time = 30/3 = 10 second.
