Sorry about that. I'll answer your questions in order... 1. The water is flowing through the pipe, but the velocity is not determined yet. I can make it as fast or slow as I want so long as I can dispense 8oz of water in 2 minutes which is what I need to cool (sorry for leaving that...

I was asked to determine how much Air is needed to cool a copper tube. The air will be blowing on the outside surface of the tube as there will be water running through the tube. The starting temperature of the water will be 70°C and the goal end temperature is 35°C...all done in less than 2...

Great! Thank you! I knew it had to be a simple calculation, but didn't even think it'd be that simple!

I have a question about how to cool the water that's already in my cup. I already have 3-4 ounces of 70°C water in my cup and want to bring that overall temperature down to 35-38°C. The end solution needs to have 8 ounces of water. I already tried doing this with room temperature water...

edgepflow - I did all the math for my cooling rate and I came up with this... Mass = 8 ounces = 0.237 kg (approx) Specific heat of water = 4187 J/kgK Temperature decrease = 32 °C Time = 2 mins = 120 seconds Power = 4187 * 0.237 * 32 /120 = 249 W How would you suggest I determine the...

I can add a little more room temperature water, but the final solution needs to be 8oz. Thank you for the equation, I'll plug some numbers into it and see what I come up with!

I'm trying to cool 8 ounces of 70 deg C water down to 38 deg C. I want to do this all in 2 minutes, but with as low a cost as possible. I was thinking of using a fan or air pressure of some short to do this. The only question I had is how do I determine the pressure or amount of air that I'll...
