PDF Air conditioning service report sheets stands for HEPA filter and blowers that generate a nonmixing stream of air. Transition depends upon many effects e. When a gas or a liquid flows through a pipe there is a loss of pressure in the fluid because energy is required to overcome the viscous or frictional forces exerted by the walls of the pipe on the moving fluid. The pressure measurements upstream p flow rate to start each of the experimental runs in order to purge the venturi meter of all air. The pitot tube was invented by the French engineer Henri Pitot in the early 18th century and was modified to its modern form in the mid 19th century by French scientist Henry Darcy. The third experiment uses the ADV. The water density and viscosity at this temperature were taken as 998. Figure 1. A display is included for information or advertising. 8. It is the objective of this experiment to enable pressure loss measurements to be as pipe bends valves and sudden changes in area of flow. A.
