**Planewall_Q_ND**

The function **planewall_Q_ND(Fo, Bi)** returns the non-dimensional heat transfer to a bounded plane wall with one edge exposed to convection (x=L) and the other adiabatic (x=0). The supplied values, Fo, Bi represent the Fourier number and Biot number respectively. The non-dimensional heat transfer is the ratio of the actual to the maximum heat transfer into the wall. A separation of variables technique is used to solve for the temperature, as explained in section 3.5.2 of Nellis and Klein.

**Output:**

**Example:**

$UnitSystem SI K Pa J

Fo=0.6

Bi=1.5

Q_hat=planewall_Q_ND(Fo, Bi)

Q_max=1000 [W/m^2]

Q=Q_max*Q_hat

{Solution:

Q=457.4 [W/m^2]

Q_hat=0.4574}
