Specific retention (S r), specific yield (S y) and total porosity (n) (from Heath 1983). Specific yield is defined as the volume of water released from storage by an unconfined aquifer per unit surface area of aquifer per unit decline of the water table. Bear (1979) relates specific yield to total porosity as follows: n = S y + S r

HOW TO ESTIMATE YIELD OF CONCRETE FOR VOLUME BATCHING ...

1. By Rule of Thumb. The rule of thumb may be used to estimate the approximate yield of concrete from a given concrete mix, when batched by volume. If the proportion of concrete is a:b:c i.e., if a parts of cement, b parts of sand and c parts of coarse aggregate are mixed by volume, the resulting concrete will have a volume of (2/3)* (a+b+c). 2.
