Kerosene with a relative density of 0.78 and dynamic viscosity () of 0.002 Pas flows from an upper storage tank under a pressure of 50kPa (gauge) to a lower vented storage tank, through three pipes of diameters/lengths: 30mm/50m, 25mm/50m and 20mm/20m connected in series as shown in the figure below. The difference in level from the upper to the lower tank is 20m. Minor losses are negligible, and the pipes are extruded and can be considered to be smooth. 50 kPa 50m 30 50 m 25 20m 20 For the piping system shown, determine: (a) the total head loss in the system; (b) the total equivalent length based on the 25mm diameter pipe; (c) the volumetric flow rate (using an initial trial friction factor value f = 0.02 and performing 3 trials).
