A cylindrical tank of area 5m2 contains water filled to a height of 10cm. A hole of area 0.005m2 is present at the bottom. What is the time required for the water level to become half?
A cylindrical tank, filled with water, has an area of 10m2. A piston covers its entire top surface. A uniformly distributed load of 1000N is applied on the piston from top. A hole of area 0.001m2is at the bottom of the tank. Find the speed of efflux when the height of water level is 0.1m .
Assume a ball is flying through air at rest. The speed of the centre of the ball is 5m/s (î). If the ball is spinning as shown below, find PB – PA. The ball has a radius (R) of 0.1m. Consider the speed of the ball to be constant as it passes through air. Let density of air be 1kg/m3. ω = 1(&jcirc; X î) rad/s.
Area 1 = 10m2, Area 2 = 5m2, rate of flow is 50m3/s. Find the value of H if the tubes contain mercury. Given that liquid flowing in the venturi tube is water.
Water having density ‘⍴’ is flowing (steadily) downwards in the given tube. What is the relation between PA & PB?
A cylindrical tank of Height H has a hole on its side. It is kept on a flat surface. Assuming that hole’s area is much smaller than the area of the tank, what should be the distance of the hole below the top surface so that water coming out of the hole travels the maximum horizontal distance at the instant when the height of water is H?
What will be the relation between H & L?
The speed of efflux, in case of a tank with a hole at the bottom, depends upon which of the following factors? Assume that the area of the tank is > > area of hole.
In which of the following conditions can the Bernoulli equation not be used?
Consider a tank of height 20m filled with liquid of density 100kg/m3. The area of tank is 10m2. If the tank has a hole of area 2m2 at the bottom, find the speed of the liquid flowing out through the hole when the height of liquid in the tank is 10m . Assume speed of liquid descending at top of tank is 5m/s.
