will rate!!
An orifice meter (see Figure 3.2-1) is to be calibrated for the measurement of the flow rate of a stream of liquid n-octane. The differential manometer fluid has a specific gravity of \( 1.60 . \) The calibration is accomplished by connecting the orifice meter in series with a rotameter that has previously been calibrated for \( n \) octane, 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.
For each of the given readings, calculate the pressure drop across the orifice, \( \triangle P(\mathrm{~mm} \mathrm{Hg}) \).
Expert Answer
specific gravity of liquid = density of liquid/density of water, density of water =1000 kg/m3, density of manometer liquid = specific gravity* density of water =1.6*1000 = 1600 kg/m3 density of n-octane = 700 kg/m3 pressure difference= height of liqu
