Thanks a Lot Mr. Quark for your time and help. I will do the balance with enthalpy. Gby. e.z.

Good Morning. Well, i am looking for any relation or equation about the heating of water using steam in contact and mix directly . Specifically i want to know heating rate or heating time in waters vessels at atmosferic pressure. I know it`s a termodinamics and mass transfer problem, but i need...

Good afternoon W.C. Use View and after render in the tools bar. click save as and choose in a dialog box type file jpg. I hope you will do succesful. greetings e.z.

Good Morning. Yes, i am gree with 25362, you have for this case an unsteady state heat transfer situation on body 1. Part of its energy will transfer from hot side to cold side, because no uniform temperataure distribution in the body 1. In other hand the body 2 will emits energy to the body 1...

Hello. You can get information in White Frank, or Hansen Fluids Mechanical. There is good information and methods for energy loss calculations. good luck

Hello Julio. I don´t know what you want? The Hidraulic Institute is a good begining. For steam or air i recommend Crane Manual, Arsmstrong manual, spirax sarco guidelines, Spence guide. you must specify the fuid and operation conditions. regards

Hello. The Pressure Vessel handbook wrote for professor Eugene F. Megyesy contains good information about volume of heads, pg 402. have a good time GBY

Oh excuse please the few data. Well, the cylinder is made in borosilicate 3.3 or Pyrex. diameter is 90 mm (3.54") thickness= 2.5 mm (0.098")(thickness to check) the working pressure is 30 psig. (max) temperature max= 120ºC (248ºF ) Referent to thermal shock, the inicial temperature is 32ºC and...

We have a stand for fluid steam demostration. There is steam traps with glass body and steel. I need know "theorical" equation for determinate the thickness o allowable pressure in a tube (cylindrical) of glass, specifically borosylicate 33. We working, in the laboratory with 30 psig max...

I know that the schedule and the fluid are important to determinate the kind of piping for an new installation. For steam supply in a common power plant 150# or 300#, what is it as the suggested pipe to install?, of course without considerer economical reason. (the seamless pipe is more...

Is it rigth sizing a header boiler with velocity of steam 3000 fpm? what is the correct velocity in a header boiler according code? thanks
