Heat transfer coffefficient from mass flow

AI Thread Summary
To determine the heat transfer coefficient of a pipe with a diameter of 0.006m and length of 0.01m, and a mass flow rate of 0.019 kg/s, one must first calculate the Reynolds number and the Prandtl number using the fluid's transport properties, including thermal conductivity, viscosity, density, and heat capacity. These calculations are essential for understanding the flow regime within the pipe. Once these numbers are established, standard heat transfer correlations found in resources like Perry's or Marks' handbook can be applied to derive the heat transfer coefficient. The thickness of the pipe is not a factor in this calculation. Accurate values for the fluid properties are crucial for precise results.

If we have a pipe with dimensions

D=0.006m
L=0.01m

and a mass flow of m' = 0.019 kg/s

How can we determine the heat transfer coefficient of the pipe?

The thickness of the pipe doesn't have to be accounted for..

You also need to know the transport properties of the fluid: thermal conductivity, viscosity, density, heat capacity. Calculate the Reynolds number and the Prantdl number. Then use the standard heat transfer correlations for flow in a pipe in Perry's or Marks' handbook to get the heat transfer coefficient.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
