I want to take a liquid metal, Aluminum at 700oC and pour it into a steel mold starting at 20oC. For the purpose of the question let’s say that the heat transfer is 100% with no losses to the surroundings.
Here are some numbers:
Mass = 200 g = 0.2 Kg
Ti, Al = 700oC
Cp = 900 J/Kg-K...
I'm looking for a formula that has velocity at a certain point in a pipe. I only have velocity and pipe diameter.
The problem goes something like:
A Tube with a 0.075 meter diameter has four drains equally spaced apart
with a cap at the far end. Each of the four drain...
