## Homework Statement

A common dimensionless group used in heat transfer calculations is defined as:

Nu=[itex]\frac{hD}{k}[/itex]

where h is the heat transfer coefficient, and D is the diameter of the pipe in which heat transfer takes place. Please determine the dimensions of the quantity k in terms of mass (M), length (L), time (T) and temperature ([itex]\theta[/itex]) and in terms of SI units.

## Homework Equations

Nu=[itex]\frac{hD}{k}[/itex]

## The Attempt at a Solution

So far, I've worked out that the units for h are J/(m

^{2}hr C), but I'm having difficulty expressing k in terms of what is given.

Am I wrong is thinking that J/(m

^{2}hr C) can be expressed as W/(m

^{2}K)? I'm thinking that this is relevant to the end units of k, but I am unsure if the dimensions are correct.
