The number of transfer units (NTU) method is used to calculate the rate of heat transfer in heat exchangers (especially parallel flow, counter current, and cross-flow exchangers) when there is insufficient information to calculate the log mean temperature difference (LMTD). Alternatively, this method is useful for determining the expected heat ...
Turbid creek water caused by heavy rains. The measurement of turbidity is a key test of both water clarity and water quality. [citation needed] There are two standard units for reporting turbidity: Formazin Nephelometric Units (FNU) from ISO 7027 and Nephelometric Turbidity Units (NTU) from USEPA Method 180.1.
The turbulent Schmidt number is commonly used in turbulence research and is defined as: [3] = where: is the eddy viscosity in units of (m 2 /s); is the eddy diffusivity (m 2 /s).; The turbulent Schmidt number describes the ratio between the rates of turbulent transport of momentum and the turbulent transport of mass (or any passive scalar).
Nephelometric Turbidity Unit, a measure of the cloudiness of a liquid; Nevada–Texas–Utah Retort, a shale oil extraction technology; New Threat Upgrade, a US Navy anti-air warfare ships system upgrade; NTU method uses the Number of Transfer Units to calculate the effectiveness of a heat exchanger
The Stanton number (St), is a dimensionless number that measures the ratio of heat transferred into a fluid to the thermal capacity of fluid. The Stanton number is named after Thomas Stanton (engineer) (1865–1931). [1] [2]: 476 It is used to characterize heat transfer in forced convection flows.
The ABC sitcom originally starred Michael J. Fox, who left the show after four seasons following his Parkinson's diagnosis and was replaced by Charlie Sheen
Formazine (formazin) is a heterocyclic polymer produced by reaction of hexamethylenetetramine with hydrazine sulfate.. Turbidity standards of 5, 50, and 500 NTU. The hexamethylenetetramine tetrahedral cage-like structure, similar to adamantane, serves as molecular building block to form a tridimensional polymeric network.
