  • i had not seen full video but Mr Barua is making blander at 18:50

  • Thank you Professor Barua...

  • in fig.6 the diagram is for air fail OPEN instead of fail close ....

  • One small correction in the Cv calculation,

    Fr factor is one for turbulent flow, not for laminar flow. For laminar flow it has to be calculated based on the Valve Reynolds number (Rev) from the (Rev and Fr graph).
