wetted area वाक्य

Given two boats of the same length, the trimaran has a shallower draft, a wider beam, less wetted area, and is able to fly more sail area.
As the aircraft gained speed, the wing would be pivoted to increase the oblique angle, thereby reducing the drag due to wetted area, and decreasing fuel consumption.
All three revisions refer largely to revisions of the cockpit, rather than the hull itself, which besides modernizing the keel, the wetted area of the boat did not change.
The major significant factor is friction drag, which is largely dependent upon the wetted area, the surface smoothness of that area, and the presence of any discontinuities in the shape.
The flat underbody develops lift as speeds increase and the hull rises higher in the water, which reduces the wetted area and decreases drag, allowing higher speeds to be achieved.

This results in less friction because of reduced waterline length, reduced displacement ( the amount of water needing to be pushed aside by the boat ), and reduced'wetted area '.
where C _ { fe } is the equivalent skin friction coefficient, S _ { wet } is the wetted area and S _ { ref } is the wing reference area.
The Voyager, which had so little wetted area that it flew around the world _ about 27, 000 miles _ on less than 1, 200 gallons of fuel, was almost unflyable when fully loaded.
Just as daggerboards and rudders are foils that enhance the control of a boat, assisting hydrofoils provide lift to the hull to reduce the wetted area without actually lifting the boat completely out of the water.
The Ibex was designed by Hall to investigate the reduced wetted area of the pod and boom configuration, hands off spiral stability of a gull wing, and the low speed performance of wide NACA slotted flaps.
