    HVAC How to know if a blower will be able to overcome system resistance?

    The rectangular chamber contains inclined perforated plates through which the air passes. At the top there is a blower and at the front as well as back bottom there are openings for air inlet. How do I calculate system resistance and know if a certain blower will be able to overcome it?

    Surface temperature of a Cylindrical heated rod

    I have created a design of a drier in which cylinderical heating rods are being used. I am trying to do the analysis of the system in ANSYS CFD (Fluent). In that case I have to put in the value of heat transfer coefficient. To find its value I found the relation between heat transfer...

    Surface temperature of a Cylindrical heated rod

    How can I calculate the surface temperature of a Cylindrical Heating rod after some time interval? There is internal heat generation in the rod and convective heat transfer to the surroundings.

    I Solve ln(a/b+1) Using Identity ln(a+b)=ln b + ln(a/b+1)

    The identity keeps repeating itself in the solution, I want to take ln of {e^(-6.7/(T-292)) + 0.56/(T-292)} / {3/(T-292)}

    I Solve ln(a/b+1) Using Identity ln(a+b)=ln b + ln(a/b+1)

    How to solve "ln(a/b+1)" after applying the identity "ln(a+b)=ln b + ln(a/b+1)" ? where "ln" is natural log, a and b have variable values in them.
