TrialandError Solution for Heated Hydraulic Drainage. In a hydraulic project a cast iron pipe having an inside diameter of m and a m length is used to drain wastewater which is also being heated from deg C to deg C Use an average temperature of deg C for bulk physical properties. Assume that the pipe wall temperature is an average of deg C higher than the average bulk temperature so that a correction can be made for the effect of heat transfer on the friction factor. The available head is m of water. Neglecting any losses in fittings and joints in the pipe, calculate the flow rate in msHint: Assume the physical properties of pure water. The solution is trial and error since the velocity appears in NRe, which is needed to determine the friction factor.
