Chapter 18, Problem 30P

Temperatures are measured at various points on a heated plate (Table P18.30). Estimate the temperature at

(a) $x=4,y=3.2,$

(b) $x=4.3,y=2.7$.

TABLE P18.30 Temperature $\left(\text{°C}\right)$ at various points on a square heated plate.

$y=2$	85.00	64.49	53.50	48.15	50.00
$y=4$	70.00	48.90	38.43	35.03	40.00
$y=6$	55.00	38.78	30.39	27.07	30.00
$y=8$	40.00	35.00	30.00	25.00	20.00
