How much water is needed to cool gas by 33 degrees?

How much water is required to cool 50,000 m3/h of coke oven gas from 75 degrees to 42 degrees, using cooling water at 32 degrees? Assume the gas density is 1.3 kg/m3 and the specific heat is 1.26 kJ/(kg*K)
This is related to the temperature of the cooled return water; assuming the return water temperature is t, the amount of cooling water required is 5000*1.3*1.26*（75-42）/4.2/（t-32) kg/h
Generally, when the return temperature of the cooling water is no higher than 40 degrees, the water consumption is = 1.26*50000*1.3*（75-42）/4.2*(40-32)
