    Calculating heat transfer coefficient

    I've been getting a really low reynolds number so I'm not sure if I'm doing this right. If someone could check my work that'd be great. 1.I start with Vol. flow: .5gpm*(3.785liter/gall)*(.8gm/liter)=1.51 gm/min mass flow. 2. Then I solve for velocity: v=M/(rho*(xArea)/2)...

    Calculating heat transfer coefficient

    Great. now for the x-sectional area would that just be half the x-sectional area for a full pipe of this diameter? Thanx.

    Calculating heat transfer coefficient

    Hello. I am attempting to design a system that involves running an external half-pipe cooling jacket around a firepot assembly. This jacket is limited in size to about a 1.5" radius and will be using ammonium hydroxide as the cooling agent. The NH4OH will only be flowing @ .5gpm. The firepot...
