WebTranscribed image text: Consider the flow of engine oil (Cp 2048 J/kg K) through a thin-walled copper tube at a rate of 0.3 kg/s. The engine oil that enters the copper tube at an inlet temperature of 80°C is to be cooled by cold water (Cp 4180 J/kg K) flowing at a temperature of 20°C. It is desired to have an exit temperature of the engine ... WebOct 24, 2024 · Tells us how the oil will flow in cold conditions. The smaller the number, the better will be the flow. For instance, a 5W-30 oil will have a better cold flow than 10W-30 engine oil. The number in the following part indicates how the finely the oil will flow at normal operating temperature.
