Question

Given that for a flow process the steady flow equation is

q- w = (u2 – u1) +(P2v2 – Pv1)+
+ g(z2- zı)
2
where: q is heat per kg to or from the system (J/kg)
w is work per kg to or from the system (J/kg)
u is the internal energy per kg (J/kg)
Pis the pressure (N/m²)
v is the specific volume or volume per kg (m³/kg)
C is the velocity of flow (m/s)
g is gravity (m/s²)
z is height above the datum (m)
subscript 1 and 2 denotes inlet and outlet, respectively.
Determine the value of work, w in J/kg, if
q = 10*10³ J/kg
u2 = 0.5*10° J/kg, ui-2.0*10° J/kg
P1 = 6.2*10$ N/m?
Vi = 0.37m³/kg, v2 = 1.2m³/kg
Ci= 300 m/s, C2 = 100 m/s
P2 = 3*10$ N/m?
g = 9.81 m/s²
zi = 2m, z2 = 2m
