A system is devised which burns the carbon in 3 times excess air to yield complete combustion of the carbon to CO2 whilst heating process water from 15-90°C. The carbon and air feed to the system are at 40°C and 25°C,
respectively whilst the combustion gas outlet is 70°C. Given the data in table A2 below calculate the following:
(i) The approximate heat capacity of the outlet stream.
(ii) The heat transferred to the process water in kW.
(iii) The mass flow rate of hot water produced by the system.
