What is the non erodible velocity in designing channel?
What is the non erodible velocity in designing channel?
Minimum Velocity is 2-3 ft/sec -> non silting velocity to prevent aquatic growth.
What is non erodible?
Nonerodible means a material, e.g., riprap, concrete, plastic, etc., that will not experience surface wear due to natural forces.
What is erodible channel?
Erodible channels are designed for subcritical flow conditions with value of Froude number less than 1. A trapezoidal channel section is usually used for erodible channels.To design these channels, first an appropriate value for the side slope is elected so that the sides are stable under all conditions.
Which of the following is a non erodible insert?
The Non-erodible ocular inserts include Ocusert, and Contact lens. In the bioerosion mechanism, the insert is comprised of a matrix of bioerodible material in which the drug is dispersed.
What do you mean by erodible?
vb. 1. to grind or wear down or away or become ground or worn down or away. 2. to deteriorate or cause to deteriorate: jealousy eroded the relationship.
What is trapezoidal channel?
Trapezoidal Channel is an open channel with a trapezoidal cross section where both sides have the same slope. The flow routing through a Channel Connection is described in Analysis of Connections. Parameters to specify: Length, Slope, Manning’s n, Diameter/Base Width, Height, Side Slope, see Connection Inputs.
Which of the following is a prodrug?
Examples of prodrugs that exist naturally or were produced unintentionally during drug development include aspirin, psilocybin, parathion, irinotecan, codeine, heroin, L-dopa, and various antiviral nucleosides.
Which of the following is used as mucoadhesive?
PAA and NaCMC possess excellent mucoadhesive characteristics due to the formation of strong hydrogen bonding interactions with mucin. Polycarbophil (Noveon) and Carbomers (Carbopol), PAA derivatives have been studied extensively as mucoadhesive platforms for drug delivery to the GI tract.
What is exportation mean?
the act of exporting
: the act of exporting also : a commodity exported.
What is an example of erode?
To erode is defined as to gradually wear away, or to be gradually worn away. When water continually washes over soil and begins to wash away that soil, this is an example of a situation where the water erodes the soil. The running water eroded a gully.
Why canal is trapezoidal in shape?
Why a trapezoid? The short answer: CAP’s specific trapezoidal shape is a balance of hydraulic efficiency and constructability. Take a look. Water in the canal is flowing by gravity and generating friction where it is in contact with the canal lining on its bottom and sides.
What is rectangular channel?
Rectangular Channel is an open channel with a rectangular cross section. The flow routing through a Channel Connection is described in Analysis of Connections. Parameters to specify: Length, Slope, Manning’s n, Diameter/Base Width, Height, see Connection Inputs.
