Sentence examples for minimum air velocity from inspiring English sources

Minimum air velocity values were found in order to achieve 90% of thermal and air movement acceptability.

From 24 to 27 °C the minimum air velocity for thermal and air movement acceptability is 0.4 m/s; from 27 to 29 °C is 0.41 0.8 m/s, and from 29 to 31 °C is >0.81 m/s.

For example, the minimum air velocity of 0.15 m/s is the standard velocity for normal-size underground spaces; however, this value is also used as the required air velocity for diluting underground contaminants in super-large underground developments.

The main aim of this work is to investigate the air flow over the deposits of particles (including both horizontal layers and hill-shaped particles) and to determine the minimum air velocity for picking up the particles from the deposits.

Therefore the minimum fluidization air velocity to fluidize the sand particles and pressure drop are crucial hydrodynamic parameters for analysing the operation and design of fluidized bed combustors.

As with dense phase conveying, the minimum conveying air velocity for a material is a critical design parameter; however, unlike dense phase conveying, there is no significant change in its value with solids loading ratio.

Therefore, the purpose of this study was threefold: (1) to prove that PRRSV introduction via retrograde air movement through idle fans is a true risk; (2) to determine the minimum retrograde air velocity necessary to introduce PRRSV to an animal airspace from an external source; and (3) to evaluate the efficacy of different interventions designed to reduce this risk.

The capabilities of the different groups of bulk solids are considered in terms of air requirements, minimum conveying air velocities, and solids loading ratios achievable and hence their potential for conveying with regard to material flow rates and conveying distances possible.

Multi-scale characteristics of particle fluctuation velocity at the MPD (minimum pressure drop) air velocity in the acceleration and fully-developed regimes are experimentally investigated.

An existing method of representing minimum transport criteria (based on superficial air velocity and solids loading) has been found inadequate for accurately predicting the unstable boundary, especially under diameter scale-up conditions.

The experiments were carried out varying solid particle mass, coating suspension flow rate and excess air velocity in relation to the minimum fluidization velocity working with a temperature of 70 °C.
