The Fluid And The Force Acting On The Flat Plate Were Measured

Summery In process industries the flowrate of a fluid can be defined by measuring the pressure drop across pipes and fittings while the fluid passing through them. In this laboratory experiment, the flowrate of the fluid and the force acting on the flat plate were measured. While comparing the experimental values for pressure drop with theoretical ones, it became clear that in most cases, experimental values exceed theoretical ones. The reasons of deviations from ideal theoretical values are roughness of the pipes which was not taken into account (pipes were supposed to be smooth), changes in temperature (constant room temperature (20 0C) was assumed), compressibility of air (it was supposed that air is incompressible) and debris in pipes. 1. Introduction Because of safety circumstances, it is very important to control pressure loss through pipes in order to ensure a process plant to operate in a safe way. To design a safe plant operation, pressure loss across the process plant should be taken into account and it can be manageable by making changes in flowrate of the fluid. The aims of this experiment are to measure pressure drop across different pipes,fittings, venturi meter and orifice plate, to figure out momentum change of air due to jet impingement on a flat plate and finally, to discuss differences between practical measurements and theoretical predictions. 2. Theory 2.1 Smooth pipe In the last laboratory experiment, general pressure loss across straight pipes was
