What is the typical flow rate for a pipe with a diameter of 50? Water, galvanized pipes, cooling water; temperature: 30°C. There is a case where the furnace body is cooled using circulating water. After insulating the furnace body, the temperature inside it reaches 150°C. The furnace body is made of 16MnR material with a thickness of 18 mm. Circulating cooling water is used in the jacket to lower the temperature to around 30 degrees; the temperature of the cooling water itself is around 20–25°C. What is the required flow rate for this purpose? I seek advice from experts. @leo_0088 @XinruiChemical @zhjnavy015 @szwbuaa @li*nji @geddddd @654262293 @1111111
Based on our factory, our workshop, and my experience, the upper limit for the flow rate of cooling water is generally within 2 m/s. But this calculation result is too harsh; it’s only at the level of 15 t/h.
When water is used as the medium, a flow rate of 0.5–3 m/s is generally considered economical. For smaller pipe diameters, a higher flow rate can be chosen; for a pipe diameter of 50 mm, 3 m/s is entirely acceptable
The flow velocity for a pipe with a diameter of 50 should not be too high; pressure loss is the main consideration, and it should be kept below 2 m/s
It’s obviously a calculated flow rate; with all the given conditions being so clear, why is it still necessary to specify a flow rate? Is the flow rate artificially determined? ? There must be a way to control the flow rate, right?
The flow of fluids is primarily driven by pressure differences (and, of course, by the law of conservation of mechanical energy, the Bernoulli equation); it should be considered as a whole within the piping system.

One should first determine a reasonable flow rate themselves
