Consider a stirred-tank containing water (p-103kgmS, C-Ical ge C) at constant volume, V, of 20 m3 with equal water flow in and out (w-104 kghr, At steady state, the inflow temperature, Ti was 40°C and the temperature in the tank was 90°C. The system was heated by condensing saturated steam passing through the heating coil (AHy of steam at the coil pressure-600 calg). At a certain time, the flow in the heating coils immediately doubles. Determine: 1. The new steady...
