Answer: 43.8 kg/min
Volume of the fuel = Volume of the tank=
Here, we are considering that the given relative density is with respect to water.
Density of fuel =Relative Density of fuel ×Density of water
Density of fuel

Mass of the fuel filled= Density of fuel ×Volume of the fuel
Mass of the fuel filled


Hence, mass flow rate from the pump is 43.8 kg/min.
