How to determine the diameter of the power piping in a reaction vessel
Thread Content
If I know the amount of cooling required to reduce the temperature of the medium inside the reactor to a certain level, and I have set the time required for this temperature reduction, how can I calculate the diameter of the pipe needed to convey the cooling medium?
For refrigerant media without phase changes, it is necessary to find their isobaric heat capacity Cp and density ρ on one’s own； For a refrigerant medium with phase change, its vaporization latent heat γ and density ρ are determined in order to calculate the flow rate F of the refrigerant medium. In the case of no phase change: F = (Q / τ) / (Cp * Δt), where Q represents the amount of heat removed ； τ——time ； Δt – Temperature difference of the refrigerant medium; in the case of phase change: F = (Q/τ)/γ. To calculate the pipe diameter: D = ((4*F)/((π*v)))^(-2). Where: D – Inner diameter of the pipe ； π——pi ； v —— Flow rate of the refrigerant medium (can be found in relevant manuals). D is rounded up, and the DN of the pipe is determined from ** or the industry’s pipeline series standards. Note: The units used in the calculation are provided for your reference
As shown in the calculation process above, the flow rate must first be determined before the pipe diameter can be calculated
Thank you for your detailed explanation; I am very grateful
