Pipe Cooling
Specify pipe cooling information purported to reduce hydration temperature. Pipe cooling can be performed by casting pipes inside the concrete structure and pumping a low temperature liquid through the pipe. The low temperature liquid will prevent increase in temperature due to hydration. Heat transfer occurs between the surface of the pipe and the convection of the flowing liquid.
From the Main Menu select Load > Heat of Hydration > Heat of Hydration Analysis Data > Pipe Cooling.

Specific Heat of cooling water Density of cooling water Inlet Temp of cooling water Flow Rate of cooling water Inflow Time Duration of pipe cooling relative to construction stage Start: Starting construction stage and the time of application (hr) End: Ending construction stage and the time of disengagement (hr)
Diameter: Pipe diameter Convection Coefficient: Convection Coefficient of cooling pipe
Note The flowing water convection coefficients, which are recommended by the Japanese Concrete Engineering Society, represent the convection coefficients as a function of velocity. When the velocity is 20~60cm/sec then the flowing water convection coefficient is as follows: h_p = 4.75u + 43.0 where, u = velocity of low temperature liquid (cm/sec)
Enter the path of the pipe defined by nodes, which are specified in the direction of the flow.
Node No.: User-specify the node numbers directly.
