2. If a pump discharges 284 liters per minute of water whose density is 985 kg/m3
. Find (a) mass
flow rate in kg/min; (b) the total time required to fill a vertical cylindrical tank 3.05 m in
diameter, and 305 m high. Note: m = Q x ρ, where m= mass, Q=volume flow rate, ρ= density.
Volume of a cylinder is (π/4)(D2
)(h).
