4. DISCUSSION In this experiment the pressure drop was measured at different parts of the rough pipe by utilising the devices called flowmeters such as orifice meter, nozzle meter, pitot tube and rotameter. The calculated pressure drop then was related to the flow rate of the tap water. As it was stated before, the calibration of the devices was also conducted which in a way showed the efficiency of the one and the other flowmeters. After plotting the log-log curves of the mass flow rate versus the height of the manometer for orifice meter, nozzle meter and pitot tube, the graphs appeared to be linear. It means that the relation between the flow rate and the manometer reading is in the form of . * C m A h = where A is the slope of the calibration curve and C is the 10 th base exponential of the x-intercept of the curve. As it can be seen the slopes of the curves are nearly equal to 0.5 which is the theoretically expected result. The calibration curve for the rotameter was not a log-log as can be seen from Figure 3.1. The curve is linear and it states that the readings of the rotameter are directly
