Figure 7a,b Normilised Mass flow rates as a function of inclination a) 15 mm cutter b) 30 mm cutter
From Figures 7a and 7b it can be seen that the normilised flow rate at non vertical orientations is typically improved compared with the vertical operation. There is a moderate amount of noise in the captured data predominantly as a result of using the Variable Voltage Variable Frequency (VVVF) drive unit. This is an unfortunate necessity of the experimental facility and is principally responsible for the size of the error bars in the data.
