FLUID FLOW UNIT Keywords: Pressure loss‚ straight pipe‚ pipe bend‚ orifice meter‚ venturi meter. 3.1.1. Object The object of this experiment is to investigate the variations in fluid pressure for flow in straight pipes‚ through pipe bends‚ fittings‚ orifice and venturi meters. 3.1.2. Theory When a fluid flows along a pipe‚ friction between the fluid and the pipe wall causes a loss of energy. This energy loss shows itself as a progressive fall in pressure along the pipe and varies with
