Using a dipstick to measure the amount of fuel remaining in a tank The lower end of an oil dipstick with markings for minimum and maximum oil levels. Dipsticks can also be used to measure the quantity of liquid in an otherwise inaccessible space, by inserting and removing the stick and then checking the extent of it covered by the liquid.
The oil collects in an oil pan, or sump, at the bottom of the crankcase. In some small engines such as lawn mower engines, dippers on the bottoms of connecting rods dip into the oil at the bottom and splash it around the crankcase as needed to lubricate parts inside.
Dixie Chopper claims to build the world's fastest lawn mowers. The most famous example was the Jet Mower, custom built by Art Evans in 1991 using a 150 HP Solar T62 APU from a Chinook Helicopter. [7] This mower was featured in a 1993 episode of Home Improvement. Dixie Chopper's promotional video includes a brief clip from the episode. [8]
Larger lawn mowers are usually either self-propelled "walk-behind" types or, more often, are "ride-on" mowers that the operator can sit on and control. A robotic lawn mower ("lawn-mowing bot", "mowbot", etc.) is designed to operate either entirely on its own or less commonly by an operator on a remote control.
Soil acidification refers to the process by which the pH level of soil becomes more acidic over time. Soil pH is a measure of the soil's acidity or alkalinity and is determined on a scale from 0 to 14, with 7 being neutral. A pH value below 7 indicates acidic soil, while a pH value above 7 indicates alkaline or basic soil.
Water is a good polar solvent, dissolving many salts and hydrophilic organic molecules such as sugars and simple alcohols such as ethanol. Water also dissolves many gases, such as oxygen and carbon dioxide —the latter giving the fizz of carbonated beverages, sparkling wines and beers.
