LMTD calculation for a constant product

[kmic]

Hi everybody
I want to calculate the LMTD for a cooling application in an insulated storage cooling jacket tank .My issue is that the product inside temperature is constant at 4degC and not increase or decrease and the service medium circulated around the jacket is water at tcws=1degC and tcwr=3degC.

Pls’ advice.

I don't understand your issue.

LMTD

[Δ]T[sub]A[/sub] = 4 - 1 = 3[sup]o[/sup]C
[Δ]T[sub]B[/sub] = 4 - 3 = 1[sup]o[/sup]C

Can you clarify your issue?

Good luck,

To a ChE, the glass is always full - 1/2 air and 1/2 water.

Thank you Latexman my issue is that because my product is at constant temperature at constant volume container and the service medium vary i wondering if i can use the LMTD for constant temperature formula to solve my problem or doesn't play any role.

OK, so you got LMTD = 1.82[sup]o[/sup]C?

Good luck,
