Part A - The three tanks shown in the figure below are connected by new cast iron pipes (ɛ = 0.26 mm). The diameter and length of each pipe are stated in the figure below. The flowrate in channel 1 is 50 m3/s. Determine the flowrate in pipes 2 and 3 and the required pump power. Neglect minor losses.

EES Coding

 

 

Part A - The three tanks shown in the figure below are connected by new cast iron pipes (ɛ = 0.26 mm).
The diameter and length of each pipe are stated in the figure below. The flowrate in channel 1 is 50
m³/s. Determine the flowrate in pipes 2 and 3 and the required pump power. Neglect minor losses.
Elevation = 0 m
Elevation = 200 m
(Datum)
Dia = 0.8 m
Pump Dia = 1.0 m L = 500 m
L = 200 m
(2) Elevation = 150 m
(1)
Dia = 1.2 m
L = 300 m
Clearly show your work and explain the setup of the Bernoulli equation and conservation of mass. If you
use EES, please include the script and screen shot of the output. State the solution of the pump power
and flowrates in pipes 2 and 3 clearly - do not just show the EES output.
Part B – Using the script, perform parametric study on the effects of
a. Increasing the flowrate in pipe 1 from 50 to 100 m³/s on the pump power
b. Increasing the pipe length of channel 1 on the pump power (for 50 m³/s flowrate)
c. Increasing the elevation of tank B from 200 m to 600 m to the pump power (for 50 m³/s
flowrate)
