Flow Measuring Apparatus
ABSTRACT
The flow measuring apparatus is designed to study which the most preferable flow meter from different typical methods of measuring the discharge of an incompressible fluid. This can be identify by measuring the flow rate and the head loss with later to be compared to the different flow meter which is venture meter, orifice meter and rotameter.
INTRODUCTION
The objectives of this experiment are to demonstrate the characteristics of some various commonly used methods of measuring fluid flow rates and to identify the head losses associated with each flow measuring apparatus. The devices to measure the flow rate are determined by using a venturi meter, an orifice plate meter and a rotameter. Head losses associated with each meter are determined and calculated. This experiment is related to the applications of the Steady Flow Energy Equation (Bernoulli’s Equation). It can be written in the form; p1ρg + 122g + z1 = p2ρg + 2 2g + z2 + ∆H12 (1)
Where pρg is termed the hydrostatic head. 22g is termed the kinetic head (is the mean ratio of velocity i.e. the ratio of volumetric discharge to cross-sectional area of tube) z is termed potential head p/ρg + 2/2g + z represents the total head.
