Foreced Convection in a Heated Tube

Foreced Convection in a Heated Tube

Foreced Convection in a Heated Tube

(OP)
I am looking for a formula to estimate the temperature rise of pressurized water in a heated pipe.  The relevant information are:

Water pressure:10,000 psi or 69 MPa
Water flow rate: 0.1 gal/min or 0.378 liter/min.
S.S. High-pressure tube: wall thickness & ID = 2.12 mm.
                         tube length: 6 m
                         thermal conductivity = 21 W/mK.   
Temperature of pipe wall 200 deg C.  
Inlet water temperature  20 deg C.  
Heat transfer coefficient of water: 500 - 1000 W/m2K.

What is the water temperature at the exit of the tube ????

RE: Foreced Convection in a Heated Tube

Is this a homework problem?

No, this is an experiment I am setting up for a research project.

RE: Foreced Convection in a Heated Tube

every basic text on heat transfer will have the equation for T(exit) in this situation.
especially look in the "heat exchanger" chapter under Log Mean Temperature Difference.
