SECTION 2 : Pool Area Calculation

**2.1 POOL SHAPE EXAMPLES**

For most pools the surface area is the most important information
required to calculate the area of Collector Array need.

The surface area of most pools can be approximated by considering
the pool shape to be a combination of more common shapes.

The approximate surface area can then be easily calculated.

**(i) Square or Rectangle**

L = 3m Area = Length x Width
W = 4m 3m x 4m
= 12 Square Metres

**(ii) Trapezium**

L = 8m Area = L x __(W1_+_W2)__
W1 = 4m 2
W2 = 5m = 8 x __(_4_+_5_)__
2
= 36 Square Metres

**(iii) Circular**

D = 4m Area = (_3.14_x_D²_)
4
= (_3.14_x_4_x_4_)
4
= 12.6 Square Metres

**(iv) Combination of Shapes**

This example shows how to use three basic shapes to calculate
the surface area of a swimming pool.

D1 = 3m This pool can be broken up into a
L2 = 5m trapezium and two half circles.
D3 = 4m

Total Area = Area 1 + Area 2 + Area 3
(Semi Circle) (Trapezium) (Semi Circle)
1 / 3.14 x 3² \ 5 ( 3 + 4 ) 1 / 3.14 x 4² \
= - x | --------- | + ----------- + - x | --------- |
2 \ 4 / 2 2 \ 4 /
= 3.5 + 17.5 + 6.3
= 27.3 Square Metres
**
Surface Area = 27.3 square metres
Location = Zone B
Exposed to = Yes
strong winds
More than 45 = Yes
from equator
**

**The pool used in this example will be used throughout as the
basis for sizing and collector location.**
