Leaving some change on the restaurant table is one way of giving a gratuity to the restaurant staff. A gratuity (often called a tip) is a sum of money customarily given by a customer to certain service sector workers such as hospitality for the service they have performed, in addition to the basic price of the service.
The tip-speed ratio, λ, or TSR for wind turbines is the ratio between the tangential speed of the tip of a blade and the actual speed of the wind, v. The tip-speed ratio is related to efficiency, with the optimum varying with blade design. [1] Higher tip speeds result in higher noise levels and require stronger blades due to larger centrifugal ...
Triisopropyl silane (TIPS) is an organosilicon compound with the formula (i-Pr) 3 SiH (i-Pr = isopropyl). This colorless liquid is used as a scavenger in peptide synthesis. It can also act as a mild reducing agent. In peptide synthesis, TIPS is used as a scavenger for peptide groups

Polar coordinates at the crack tip. In fracture mechanics, the stress intensity factor (K) is used to predict the stress state ("stress intensity") near the tip of a crack or notch caused by a remote load or residual stresses. [1]
The advance ratio is the inverse of the tip speed ratio, , used in wind turbine aerodynamics: [6] μ = λ − 1 {\displaystyle \mu =\lambda ^{-1}} . In operation, propellers and rotors are generally spinning, but could be immersed in a stationary fluid.
Titanium(III) phosphide (TiP) is an inorganic chemical compound of titanium and phosphorus. Normally encountered as a grey powder, [ 1 ] it is a metallic conductor with a high melting point. [ 2 ] It is not attacked by common acids or water. [ 1 ]
is ratio of hub to tip diameter; is the specific speed; Cordier diagram can be used to determine specific speed and impeller tip diameter . Accordingly solidity ratio and hub-tip ratio (range 0.3-0.7) can be adjusted.
