Water is being heated in a straight pipe with an inside diameter of 2.5 cm. The heat flux is uniform qW = 10ʻ w/m² and the flow and temperature fields are fully developed. The local difference between wall temperature and the mean temperature of the stream is 4 °C. Calculate the mass flowrate of the water stream and verify that the flow is turbulent. Evaluate the properties of water at 20 °C.
