Question
Define Overall Heat transfer coefficient.
 Question Submitted By :: Mechanical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
The overall heat transfer coefficient U is a measure of the
overall ability of a series of conductive and convective
barriers to transfer heat. It is commonly applied to the
calculation of heat transfer in heat exchangers, but can be
applied equally well to other problems.
 
Is This Answer Correct ?    22 Yes 9 No

In volute casing the discharge area is more. so as per bernoulli's principle the pressure must be reduces also from the basics, pressure = Force/Area. so pressure and area are inversily proportional. By considering these two basic rules pressure must be reduces. But in any centrifugal pump, the pressure is increasing. How the velocity is converted into pressure. In my view only head is increases but how the pressure increases?   2
