A building has a heating load of 50 kW. The building is heated with a hot water hydronic system using local radiators and circulating hot water. A heat pump is used to heat the circulating water from 35°C to 50°C. What kg/s water flow is needed in the hydronic system? (Note: ?h = CP?T. See Table A3 for CP of water.)
