Answer :
The time taken for the water tank to empty completely is 3200 s.
The given parameters:
- Mass of the water, m = 43.2 kg
- Mass flow rate of the water, Q = 0.0135 kg/s
What is mass flow rate?
- Mass flow rate is the rate at which the mass of a known substance discharges over a given period of time.
The time taken for the water tank to empty completely is calculated as follows;
[tex]t = \frac{m}{Q} \\\\t = \frac{43.2 \ kg}{0.0135 \ kg/s} \\\\t = 3200 \ s[/tex]
Thus, the time taken for the water tank to empty completely is 3200 s.
