Problem $2$

$100lb\frac{m}{h}r$ of oil at $130F$ is needed for a process modification. The oil will be available at $70F,$ so a plant engineer has designed a heater consisting of a $1in.$ ID tube, $10ft$ long, the wall of which will be maintained at $215F$ by condensing steam. Will the heater work as required?

Properties of the oil may be assumed constant at the following values:
