Thermo conservtion of mass

  1. May 13, 2009 #1
    1. The problem statement, all variables and given/known data
    Water enters the constant 130-mm inside diameter tubes of a boiler at 7 Mpa and 65oC and leaves the tubes at 6 Mpa and 4500C with a velocity of 80 m/s. Calculate the velocity at the inlet and the inlet volume flow rate

    2. Relevant equations



    3. The attempt at a solution
    so i thought i could find mass flow rate at state 2, then use this to fine velocity at state 1 but i cannot find the specific volume at state 1

    mass flow rate=(1/v2) A V2=20.3538kg/s
    massflowrate=(1/v1)A V1
