Is there a formula for calculating the volume of fluid in the tubes of a u-tube heat exchanger?
Thanks alanraym. I've got the straight length but how to calculate the bent part.
They get progressively smaller when the tubes are near the centre of the shell.
at any point in time the volume of fluid in the tubes is simply the volume of a single tube, Vt, multiplied by the the number of tubes, N.
Vt = ((pi*d^2)/4)*L
where d is the diameter of the tubes, and L is the length of the tubes. then,
Total volume = Vt*N
