Q3/ A flat plate 1.5 m long and 0.3 m wide is towed at 3 m/s in a towing basin containing water (u-1x103 Pa.s), and the drag force is observed to be 14 N. Calculate the dimensions of a similar plate which will yield dynamically similar conditions in an airstream (101.4 kPa, and u=1x10$ Pa.s) having a velocity of 18 m/s. What drag force may be expected on this plate?

Stair construction and layout

Stair is a type of vertical transportation in a building which consist of a series of steps in a flight of stairs that enable the vertical movement of people and materials from one floor to another. A staircase consists of steps that comprises of riser & tread, handrail, baluster, stair stringers, newel post and waist slab. The construction of staircase with all the components is termed as stair construction. A staircase is an enclosure that contains the entire stairway. The materials used for the construction of stairs are bricks, reinforced cement concrete, stone, lumber, steel and a combination of these materials.
