Does the water flow rate in the spiral plate type 1 heat exchanger change depending on the diameter of the inlet pipe?
Thread Content
A 100-square-meter spiral plate type heat exchanger with a plate spacing of 14 mm. According to the available data, the water flow rate is 49.4 m3/h, and the diameter of the inlet pipe is 125 mm. If the area of the heat exchanger is reduced to 50 square meters while all other parameters remain unchanged, will there be any change in the water flow rate?
The water flow rate for a pipe with a diameter of 125 mm is generally 88.3 m3/h. Has this value taken into account the effect of the plate spacing on the flow rate?
When calculating the heat exchange area, it is generally done based on the flow rate, with little consideration given to the effect of changes in the heat exchange area on the flow resistance; the impact should be minimal.
