Question 152
XE-GNAT2 marksNeeds review
Apple juice flows through a steel pipe having thermal conductivity of 50 W m⁻¹ K⁻¹. The outer surface of pipe is exposed to ambient environment. The inside diameter and thickness of the pipe are 3 cm and 1.5 cm, respectively. The overall heat transfer coefficient based on inside area is 25 W m⁻² K⁻¹. If the internal convective heat transfer coefficient is 30 W m⁻² K⁻¹, the external convective heat transfer coefficient (in W m⁻² K⁻¹) will be ________ (round off to two decimal places).
