What is difference between measured variable ,controled variable and manipulated variable ?Please reply sir.
@SPEC786 4 ай бұрын
@@naveenpandey3255 Thanks for your question. Measured variable is the process parameter to be measured for control purpose. For example if you want to control the process temperature in a reactor, you have to measure the temperature first and compare with set point temperature in a temperature controller. The measured temperature is the measured variable. The output of the controller is used to vary another process variable through a control valve. This may be steam or cooling water. This variable is called manipulated variable. The controlled variable is usually the measured variable. Hope this explanation is useful

Good video. Please explain what happens if vaporization in reboiler outlet increased from 25 to 50%
@SPEC786 6 ай бұрын
Thanks for your question. There is long explanation for this question. Heat transfer process in boiling and vaporization is complex than single phase heat transfer process. To keep the explanation short, higher vapour fraction will be result of higher heat flux. The larger vapour content will blanket the heat transfer surface which will lead to decreased heat transfer. Heat transfer will transition to film boiling which is not desirable

RRF is not in years but in times of demand if PFD is 0.01 ( RRF=100) that means that this function can fail once over 100 demands (rquests) of execution. of course this will be in 1 year from yearly maintenance to an other
@possession3929 9 ай бұрын
can you elaborate with numbers when you say reducing the flow rate will decrease head loss by square of the flow rate @15:45. So if you decrease flow rate by 100, then head loss decreases by 10? im confused with the wording

at 15:24, with pressure drop increase with increasing vaporization, how does this decrease circulation rate?
@SPEC786 9 ай бұрын
In thermosyphon reboilers the driving force for thermosyphon circulation is the differential head available at the inlet to reboiler. This head is usually fixed for a design circulation rate. If the pressure drop is increased for whatsoever reason the head available will not be sufficient to maintain the circulation rate. So the circulation rate decreases.
@possession3929 9 ай бұрын
@15:11, I thought pressure drop decreases with increasing vaporization, but you say pressure drop increases with increasing vaporization. Could you explain how?
@SPEC786 9 ай бұрын
Thank you for the question. As the vaporization increases the vapour fraction increases in the tube. In a given tube diameter this increased vapour flow rate increases the velocity of the fluid. As the velocity increases the pressure drop increases

The bridge wall temperature is the temperature of the flue gas after the radiant heat is removed by the radiant tubes and before it hits the convection section
