    14:30 why q =h1-h4?

    • @allenmolina1269
      @allenmolina1269 4 года назад +1

      Original is h4+q=h1.... Meaning enthalphy coming from pump h4 plus the energy of boiler 'q' is equal to h1, if we arrange this q=h1-h4

    Awesome sir , but will you tell us that the method of boiler power is same to every boiler ...

    Jhaat jaise padhie hai aap sir....lots of confusion are there.... Especially at 20:00 how the formula of heat supplied have come at that place...

      H1-H6 is specific enthalpy so multiplied to mass of steam , efficiency ko devide karne se hi toh required amount of haet milega babu
      kisiko critize krna asan he bro .. just apply your mind from your side also

    sir While we Calculating the boiler efficiency by direct method we Take feed water Temperature is Equal to enthalpy is that correct are wrong

      When temp in degree centigrade then equal to enthalpy nd make sure that other values also in kcal

    plz anybody reply, how do we know steam is not superheated?

    • @georgepp98
      @georgepp98 4 года назад

      its not saying that the steam is superheated in the problem

    • @somethingaround1895
      @somethingaround1895 4 года назад

      Bro here in 2nd problem superheater is used and when superheater is used it means the steam become superheated

    Sir 28:24 boiler efficiency 81.4 != 8.13*84.4*7.47

    • @9415868687
      @9415868687 7 лет назад

      I think boiler efficiency must be N0 = Nb+Ne+Ns
