    I desperately need help with a equation. During a planning stage of a steam plant it was determent that 21 650 kg steam per hour at a pressure of 0.5 MPa and a temperature of 200 deg C were required.The available feed water temperature is 34,6 deg C.The efficiency of the plant is 70% and wast gasses will be used for the heating of the plant the temperature of the gasses is 760 deg C while the atmospheric temp is 15 deg C

    a)the mass of wast gas required
    b)the temperature of the gasses
    1)leaving the evaporator
    2)leaving the superheater
    3)leaving the economizer
    c)temp of water leaving the economizer

    Please help me
