Tap tails are normally 1 ⁄ 2 " or 12 mm in diameter for sinks and 3 ⁄ 4 " or 19 mm for baths, although continental Europe sometimes uses a 3 ⁄ 8 " (still imperial) size. The same connection method is used for a ballcock.
When an aerator is added to the faucet (or fluid stream), there is a region of high pressure created behind the aerator. Because of the higher pressure behind the aerator and the low pressure in front of it (outside the faucet), due to Bernoulli's principle there is an increase in velocity of the fluid flow.
Higher spin speeds, along with larger tub diameters, remove more water, leading to faster drying. On the other hand, the need for ironing can be reduced by not using the spin cycle in the washing machine. If a heated clothes dryer is used after the wash and spin, energy use is reduced if more water has been removed from clothes. However, faster ...
