1-A heat exchanger was used to heat a quantity of water by a torch that operates with fuel (liquefied petroleum gas) (LPG). The temperature of the water entering the heat exchanger was 40 degrees Celsius and at a rate of 4.812 kg/ min. The water temperature rose by 4 degrees Celsius within 120 seconds. What is the calorific value of the fuel used? Note that the volumetric flow rate of the fuel measured by 1 liter/min Its mass density is 8 1.802 and the specific heat of water is 4.2 kJ /kg.K (LPG flow meter)
