Only part C plz
A reservoir supplies water as shown in Fig. 1. The pipe system consists of 6 m of pipe and two 90° elbows.
All pipe is 50 mm diameter, which made from cast iron.
Zi
Ball Valve
Zz 5 cm
Z3 = 0
Figure 1: Schematic diagram of task 1.
Part A
If the system is assumed to be frictionless and the water level in the reservoir is 15 cm (Z= 20
cm):
Using Bernoulli's equation, find the water velocity at the pipeline exit.
Detennine the Reynolds number in the pipe system and the significance of this Information.

Part B
Taking in your consideration the head losses accumulated by the fluid when flowing in the pipeline:
Now determine water velocity at the pipeline exit as a function of time.
Note that friction factor f can be calculated by using Blasius formula (f = (100 * Re )025 ) if
Reynolds number is less than 105
