Two streams of water are mixed to form the feed to a boiler. Process data are follows:

Feed stream 1 - m1= 128 kg/min with H1= 143 kJ/kg

Feed stream 2 - m2= 62 kg/min with H2= 270 kJ/kg

Outlet stream 3 - H3= 2,936 kJ/kg

Calculate the required heat input to the boiler in kJ/min.

Assume negligible change in potential and kinetic energy.

Report your answer up to 2 decimal points. Do not truncate any intermediate steps, but only the final result.
