Water is discharging out of a tank via a pipe with length L = 4.2 m and diameter D= 3.5 cm into an unconnected reservoir (note the free-flowing jet starting at the end of the horizontal pipe section in the figure below). The water level in the tank above the centre of the pipe remains constant at H = 4.2 m (see figure below). You can assume a density of waterp= 1001 kg/m³, dynamic viscosity of water u = 0.001 Pa s and acceleration due to gravity 9.81 m/s². You can assume that there are no local losses.

Transcribed Image Text:Water is discharging out of a tank via a pipe with length L = 4.2 m and diameter D = 3.5 cm into an unconnected reservoir (note the free-flowing jet starting at the end of the
horizontal pipe section in the figure below).
The water level in the tank above the centre of the pipe remains constant at H = 4.2 m (see figure below).
You can assume a density of water p = 1001 kg/m³, dynamic viscosity of water u = 0.001 Pa · sand acceleration due to gravity 9.81 m/s2.
You can assume that there are no local losses.
