The diameter of the water inlet of the 5 kilowatt turbogenerator is 50 meters. According to the request for relevant information, the water inlet volume of the 5 kilowatt hydroelectric generator is relatively large, so the calculations require a water inlet diameter of 50 meters to meet the inlet volume of water. A 5 kilowatt turbogenerator requires between 28 cubic meters and 31 cubic meters of water per hour when the water height H = 100 meters.
When the engine is running, the cooling water temperature of the diesel generator set must be maintained between 80 and 90 degrees Celsius before entering full load operation, otherwise the engine will not run properly . In winter, the ambient temperature of the diesel generator is lower and the corresponding coolant temperature is also lower. Therefore, diesel generators must be preheated before starting. When the diesel enginedevelops its maximum effective power, the coolant temperature should be around 80°. When using a diesel generator in winter, it is best to ensure the water temperature is around 80° when preparing for load operation.
