Water at 20 oC in a feed tank open to the atmosphere is discharged through a 3 m long steel pipe into another tank open to the atmosphere and at a lower level. The volumetric flow rate of the water is 5x10-3 m3/s. Friction losses at the tank outlet and tank inlet are negligible. Since the liquid level in the feed tank is 1 m, calculate the required pipe diameter. Make an illustration by drawing a figure
