Question: [ 6 ] A hot - water stream at 8 0 C enters a mixing chamber with a mass flow rate of 0 . 5

[6] A hot-water stream at 80C enters a mixing chamber with a mass flow rate of 0.5kgs where it is mixed
with a stream of cold water at 20C. If it is desired that the mixture leaves the chamber at 42C, determine
the mass flow rate of the cold-water stream. Assume all the streams are at a pressure of 250kPa.
