Answer to Question #284125 in Mechanical Engineering for xcereyann

Question

1. A pipe with an inner diameter of 15 mm and a length of 2 m is heated with a constant heat flux. 8 kg of water flows through the pipe per hour and its temperature rises from 20 oC to 60 oC. According to this;

a. Find the pipe surface temperature and the average fluid temperature as a function of pipe length.

b. Find the constant heat flux.

Answer 1

Heat flux (Ф) can be defined as the rate of heat energy transfer through a given surface (W), and heat flux density (φ) is the heat flux per unit area (Wm²).
