where is the density of the fluid, is the average velocity in the pipe, is the friction factor from the Moody chart, is the length of the pipe and is the pipe diameter. The chart plots Darcy–Weisbach friction factor against Reynolds number Re for a variety of relative roughnesses, the ratio of the mean height of roughness of the pipe to the ...
The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to a thousand psi (1000 lbf/in 2). ksi are not widely used for gas pressures. They are mostly used in materials science, where the tensile strength of a material is measured as a large number of psi. [4] The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa ...
Some recipes may require cooking at lower than 1 bar/15 psi (gauge) e.g. fresh vegetables, as these can easily overcook. Many pressure cookers have 2 or more selectable pressure settings or weights. Some pressure cookers have a lower or higher maximum pressure than 1 bar/15 psi (gauge) or can be adjusted to different pressures for some recipes ...
Flambé is a technique where alcohol, such as brandy, is poured on top of a dish and then ignited to create a visual presentation. [3]A variation of the flambé tradition is employed in Japanese teppanyaki restaurants where a spirit is poured onto the griddle and then lit, providing both a dramatic start to the cooking, and a residue on the griddle which indicates to the chef which parts of ...
In the process industry, chemical industry, manufacturing industry, and other commercial and industrial contexts, pipe marking is used to identify the contents, properties and flow direction of fluids in piping.

1.5 psi Pressure increase per meter of a water column [26] 10 kPa 1.5 psi Decrease in air pressure when going from Earth sea level to 1000 m elevation [citation needed] +13 kPa +1.9 psi High air pressure for human lung, measured for trumpet player making staccato high notes [48] < +16 kPa +2.3 psi
The 1707 wine gallon is the basis of the United States' gallon, as well as other measures. [3] The Imperial gallon was defined with yet another set of temperature and pressure values (62 °F (17 °C) and 30.0 inHg (102 kPa)). To convert a number of wine gallons to the equivalent number of Imperial gallons, multiply by 0.833111.
