Cross Sectional Area = Width x Average Depth
by math
Cross-sectional Area (width x average depth) (m2). Google mannings equation for a more precise equation. Ian
It is the area of the plane (the surface) covered by the water in the river channel. It is the product of the width of the channel, and the average depth of the river
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
To calculate Cross Sectional Area: Width x Depth
the larger the cross sectional area, the smaller the resistance
measure the channel height and then width and multiply them together
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
The cross sectional area of a slab can be found by squaring the height of the slab.
cross-sectional area = 0.5*(sum of parallel sides)*height
reduction ratio= initial cross sectional area/final cross sectional area
cross sectional area of cable * voltage drop
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
