To cool the lubricating oil, a concentric counter-flow heat exchanger (see Figure Q1) is utilized, with the water flowing via an internal pipe with an internal diameter of 0.02 m and a flow rate of 0.18 kg/s. The intake and output oil temperatures are 95°C and 65°C, respectively, as the oil runs through the outer annulus (0.04 m) at a flow rate of 0.12 kg/s.
