Steam at 42^oC enters a condenser with tubes of circulating cold water (c_p = 4184 J/kg*K at average temperature of 19^oC) entering at 15^oC and exiting at 28^oC. The condenser system has an overall heat transfer coefficient of 2525-W/m²K and the tubes have a surface area of 60-m². Hint: Condensers do not cause a temperate change in the steam, only a phase change. Find the mass flowrate required from the incoming cooling water.
