Question
how can  calculate how much steam is to be required for 
generation of 1MW electricty?
 Question Submitted By :: Mechanical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
it's calculate by this equation(p=m(h2-h1))
h= enthlpy
m=mass
p=power

p=1MW
m=?
h2=calculate by temp.& pressure steam enter turbine
h1=calculate by temp.& pressure steam exit turbine

Answer
# 5
steam rate=power generated in turbine/(change in specific
enthalpy of steam while leaving turbine);
henc,steamrequired=(steam rate * time)

Answer
# 6
no it is theoritical method,
but in real case, we should check the turbine by varying the
speed of the steam and angle of the nozzle,so 1 MW power is
to be generated,at that time we can check the steam velocity
and from that we can calculate the volume of the steam.

Answer
# 7
That is just an approximation. It depends on the enthalpy
of the steam, i.e. pressure of the steam and the degree of
superheat and/or reheat added. A ton/hour of steam at 900
psig and 375C will generate less MW than the same ton/hour
at 2850 psig and 590C. Also depends on the generator
efficiency which is generally assumed to be 80-85%.
