the water discharged by a water pump partly varies as the square of the distance and partly varies as the level of the pressure in the reservoir. When 302 liter of water is discharge the level of pressure is 8 coulomb while distance is 10 meters and when 1204 liters of water is discharge the pressure is 4 coulomb and distance is 20 meter. Find the quantity of water discharged when the distance is 50 meter with a pressure of 32 coulomb​
