A powerful contribution of the 1st and 2nd laws is to determine the design feasibility of a process/device/system. Please determ
ine the feasibility of the following flow device: a steady-state flow device in which the inlet is steam at 300and 5 bar, the outlet is saturated steam at 100 and 1 bar, the device is adiabatic and produces approximately 500 kJ per kilogram of steam passed through the device.

Answer:
V = 0.30787 m³/s
m = 2.6963 kg/s
v2 = 0.3705 m³/s
v2 = 6.017 m/s
Explanation:
given data
diameter = 28 cm
steadily =200 kPa
temperature = 20°C
velocity = 5 m/s
solution
we know mass flow rate is
m = ρ A v
floe rate V = Av
m = ρ V
flow rate = V =
V = Av =
V =
V = 0.30787 m³/s
and
mass flow rate of the refrigerant is
m = ρ A v
m = ρ V
m = =
m = 2.6963 kg/s
and
velocity and volume flow rate at exit
velocity = mass × v
v2 = 2.6963 × 0.13741 = 0.3705 m³/s
and
v2 = A2×v2
v2 =
v2 =
v2 = 6.017 m/s
