3.4.1 Reservoir
Figure 3.5 shows the reservoir, which is a PVC made and in cylindrical shape with
diameter of 0.25 m, length 0.3048 m and a capacity of 15 liters. The reservoir is kept 1 m
above the gear pump so that the gear pump will have adequate pressure avoiding it to run
dry. At the bottom of the reservoir a piping connects to the gear pump while at the top a
bypass line and the line from the loop are connected.

3.4.2 Gear Pump
The gear pump used for the experiment is a Liquiflow sealed gear pump (model 35 F),
see Figure 3.6. It is rated for a maximum flow of 12.8 LPM and maximum ∆
P
of 6.9 bar.
This pump is capable of operating at variable speed with maximum rated speed as 1750
RPM. The suction side of the pump is connected to the reservoir whereas the discharge
side is connected to a T-connector which divides the flow through the closed loop and a
bypass.
