A wet open umbrella is held up right as shown in fig and is twirled about the handle at a uniform rate of 21 rev in 44s. If the rim of the umbrella is a circle k 1 m in diameter, and the height of the rim above thefloor is 1.5 m. The drops of water spun off the rim hit the floor at a distance x from theaxis. Find x.

A wet open umbrella is held verticle and whirled about the handle at a uniform rate of 21 rev in 44 s. If the rim of the umbrella is a circle of 1 m in diameter and the hight of the rim above the floor is 4.9 m. The locus of the drop on the floor is a circle of radius

A wet umbrella is held upright (see figure). The man holding it is rotating it about its vertical shaft at an angular speed of omega = 5 rad s^(–1) . The rim of the umbrella has a radius of r = 0.5 m and it is at a height of H = 1.8 m from the floor. The man holding the umbrella gradually increases the angular speed to make it 2 omega . Calculate the area of the floor that will get wet due to water drops spun off the rim and hitting the floor. [g = 10 m//s^(2)] .

The acceleration of a point on the rim of a flywheel 1 m in diameter, if it makes 1200 rpm is

A flywheel of diameter 1 m is rotating at 600 r.p.m., the acceleration of a point on the rim of the fly wheel is

A point in the rim of a wheel 4 m in diameter has linear velocity of 16 ms ^(-1) The angular velocity of wheel is

The mass of a flywheel is concentrated at its rim

Assume that a drop of water is spherical and its diameter is one-tenth of a cm. A conical glass has a height equal to the diameter of its rim. If 32000 drops of water fill the glass completely, then the height of the glass (in cm.) is

The area of base of a conical drum is 44 m^(2) and its height is 2.1 m. Find its volume.

The rain water from a roof of 44 m xx 20 m drains into a cylindrical tank having diameter of base 4 m height 3.5 m. If the tank is just full, find the rainfall in cm.

Water is flowing through a horizontal pipe fixed at a height of 2 m above the ground as shown in Fig. 5.90. water strikes ground at a distance of 3m from the pipe. The speed of water as it leaves the pipe is:
