WebA venturi meter is a way to measure flow in a pipe. The venturi is a section of pipe where the diameter is gradually reduced to some smaller area then gradually increased to the initial diameter To measure the flow in the pipe you measure the pressure at the inlet and then again at the narrowest section of the venturi. Assuming no friction. WebFor flow in a pipe, T b is the average temperature measured at a particular crosssection of the pipe. The basic relationship for heat transfer by convection has the same form as that for heat transfer by conduction: or q = h c A (T s - T a) where q = heat transferred per unit time (W) A = heat transfer area of the surface (m 2)
