Water vapor, with a molecular mass of 18 kg/kmol, enters a nozzle at 1100[kPa], 400[C] and 30[m/s], and exits at 300[C] and 300[kPa] while giving

Water vapor, with a molecular mass of 18 kg/kmol, enters a nozzle at 1100[kPa], 400[ºC] and 30[m/s], and exits at 300[ºC] and 300[kPa] while giving up heat to the around a rate of 25[kW]. The input area is 800[cm2].

Determine:
a) The output velocity c2 (m/s):

b) Volumetric flow of steam at the nozzle outlet (m3/s)
