Hi,

please someone help me in designing a condenser for an a/c. I am asked to design a condenser in which tube area is to be calculated (Q, LMTD are found, but overall heat transfer coeficient -U is given as 5 and i dont know the source). Can anyone help me to find the overall heat transfer coefficient of a tube and fin type condenser of a refrigerator (cross flow). Is there any data book to directly find this from the parameters. Or if finding by calculation how can i get the values of convection heat transfer coefficient of inside and outside of the tube (from data book?). Thankyou in advance
