Question

A-f is one problem

a.What is the specific enthalpy and specific volume of steam at 350 c and 60 bar?

b. Is this steam super heated or saturated?

c. If this steam issuper heated, what is its degree of superheatt? If this steam is saturated, respond with "0".

d. estimate the temperature, specific enthalpy and specific volume of saturated steam at 6.2 bar.

E. If 14.0m^3/min of steam at 350c and 60 bar enters a turbine and leaves as saturated steam at 6.25 bar, what ia the volumetric flow rate of steam leving the turbine?

F. If the turbine operates adiabatically, what is the work output?

Explanation / Answer

a) h = 3043.85 KJ /kg .

v = 0.04 m^3/kg. ....................................use steam table calculator online to get these values.

b) Saturation temperature = 275.58 deg C .

Yes it is superheated.

c) Degree of super heat = 74.42 deg C

d) Temp = 160.1 deg C

h = 2757..56 KJ/kg

v = 0.3059 m^3 /Kg

e)

(14/0.04) = x/ 0.3059

x = 107.065 m^3/min.

f) m1 * h1 = m2 * h2 +W

W = m1* h1 - m2*h2

= 350 kg/min ( 286.29 KJ/kg ) = 100201.5 KJ/min
