A gas cylinder can discharge gas at the rate of 1 cc/minute from burner A and at the rate of 2 cc/minute from burner B (maximum rates of discharge). The capacity of the gas cylinder is 1000 cc of gas. The amount of heat generated is equal to 1 kcal/cc of gas. However, there is wastage of the heat as per the following table: Gas discharge @	Loss of heat
0-0.5 cc/minute	10$\%$
0.5-1 cc/minute	20$\%$
1-1.5 cc/minute	25$\%$
1.5 + cc/minute	30$\%$
(include higher extremes)
