EXPERIMENT 7 : ORIFICE COEFFICIENT MEASUREMENT INTRODUCTION From application of Bernoulli’s equation (conservation of mechanical energy for a steady, incompressible, frictionless flow) : ideal orifice outflow velocity at the jet vena contracta (narrowest diameter) is: vi= 2gh Where h is the height of fluid above the orifice. The actual flow rate of the jet is defined as: Qt= Acv Where Ac is the cross-sectional area of the vena contracta, given by: Ac= CcAo Where Ao is the area of orifice

2.016 Hydrodynamics Reading #4 2.016 Hydrodynamics Prof. A.H. Techet Potential Flow Theory “When a flow is both frictionless and irrotational, pleasant things happen.” –F.M. White, Fluid Mechanics 4th ed. We can treat external flows around bodies as invicid (i.e. frictionless) and irrotational (i.e. the fluid particles are not rotating). This is because the viscous effects are limited to a thin layer next to the body called the boundary layer. In graduate classes like 2.25, you’ll

1. Blade Design: The design of the blade does not just depend on the stress analysis; several other factors play significant roles as well. The leading edge is thicker than the trailing edge for a streamlined Flow. Furthermore, the blade should be as thin as possible to improve cavitation Characteristics; it is thicker near the flange becoming thinner and thinner towards the tip. In Addition, the blade has to be distorted on the basis of the tangential velocity. Blade design is the most complex

Aim The aim of this experiment is to determine the loss coefficient (K) for a number of bends and fittings, then to compare these results with results obtained from other more accurate sources such as textbooks. According to the results from textbooks the calculated disturbances in flow proves that velocity and pressure is lost through heat and friction.

Energy Losses in Pipes and Fittings Objectives: i. The objectives of this experiment were to firstly, measure the experimental head loss which was due to the friction which occurred in a straight pipe and compare the value with that of which was obtained using a Moody chart. Then to demonstrate that head loss gradient and flow-rate squared are proportional to each other. Summary of Theory: Fluid flows can be described in two ways. These are “laminar” or “turbulent”. Laminar (streamline)

Wyatt Engineering’s PMT: The REAL Lo-Loss® Flowtube In 1961, the performance of the first and original Lo-Loss flow tubes, which were designed and marketed by the Penn Meter Company out of Philadelphia, was documented in an ASME paper, “Design and Calibration of the Lo-Loss Tube (61-WA-80).” A year or so later, Penn was purchased by Badger Meter out of Milwaukee, and the Lo-Loss tube became the Badger Meter PMT Lo-Loss® flow tube (the “PMT” stands for “Penn Meter Tube”). Over the years, Badger
