Q1/ An orifice meter is to be calibrated for the measurement of the flow rate of a stream of liquid acetone. The differential manometer fluid has a specific gravity of 1.10. The calibration is accomplished by connecting the orifice meter in series with a rotameter that has previously been calibrated for acetone, adjusting a valve to set the flow rate, and recording the flow rate (determined from the rotameter reading and the rotameter calibration curve) and the differential manometer reading, h. The procedure is repeated for several valve settings to generate an orifice meter calibration curve of flow rate versus h. The following data are taken. VALVEX Flow Rate V (mL/s) Manometer Reading h(mm) 5 62 10 15 20 87 107 123 25 138 30 151 1- For each of the given readings, calculate the pressure drop across the orifice, AP (mm Hg). 2- The flowrate through an orifice should be related to the pressure drop across the orifice by the formula. V = KP" Verify graphically that the given orifice calibration data are correlated by this relationship, and determine the values of K and n that best fit the data. 3- Suppose the orifice meter is mounted in a process line containing acetone and a reading h = 23 mm is obtained. Determine the volumetric, mass, and molar flow rates of acetone in the line. %3D

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
