Subcooled water at 5°C is pressurised to 350 kPa with no
increase in temperature, and then passed through a heat exchanger
where it is heated until it reaches saturated liquid-vapour state
at a quality of 0.63. If the water absorbs 499 kW of heat from the
heat exchanger to reach this state, calculate how many kilogrammes
of water flow through the pipe in an hour. Give your answer to one
decimal place.
