Answer / shwan osman

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 / laxmi prasad

3 to 4 ton steam is to be required for
generation of 1MW electricty

Answer / magesh

Simple guys
to produce 1 MW of electricity 4.2 tonnes per hour of steam
is required.

Answer / abhishek giri

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

Answer / luis

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%.

Answer / supa

Specific steam consumption=design flow/design power

Answer / chaitanya pithawa

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 / tejeswararao

That is depend up on turbine design if it is seimens turbine 3.8 tons more than enough if it is triveni turbine it may 4.5tons like that and it may vary as per load curve

i woule my experiences in BARC i recently gone for the interview.. they dont consider u r dress code and all, even u can go in a jeans and tea shirt.they dont careabout u r personality , profile .. Theytest (complety) our technical knowledge.. so u have to prepare well in not only the basics but also in depth.. Even the did not consider the percentile in GATE.. One guy got 99.63 in gate but did not given medical. so u have to be very stiff and togh technically.. u should have a lot of luck too,because right panel selects u.. u dont expect what,how in Barc,only why.i amnot frightening u, i am telling u some facts i have faced.. istead of all i did it superbly and waiting for the result.. if u want more information, u can email me ,call me at any time..
