Developing a model for a low-pressure steam generator as described in the attachment.
Let the fraction f of the rw is converted into steam. Hence, the heat energy transferred to the tank will be used to raise the temperature of the water (f*rw) from Tw to T and converting into steam.
q = f*rw*L + rw*Cw*(T-Tw)
=> f = (q - rw*Cw*(T-Tw))/(rw*L) ...
The solution applies the relevant theory and associated formulae to provide a guide in developing the required model for a low-pressure steam generator.
