Bernoulli's Equations|Magnus Effect|Atomiser|Aeroplane|Pull In Due To Fast Moving Train

In deriving Bernoulli's equation , we equated the workdone on the fluid in the tube to its change in the potential and kinetic energy (a) How does the pressure change as the fluid moves along the tube if dissipative forces are present ? (b) Do the dissipative forces becomes more important as the fluid velocity increase? Discuss qualitatively.

Some gas at 300K is enclosed in a container. Now the container is placed on a fast moving train. While the train is in motion, the temperature of the gas

Some gas at 100 K is enclosed in a container. Now the container is placed on a fast moving train. While the train is in motion, the temperature of the gas

An aeroplne A is flying horizontally due east at a speed of 400 km//hr .Passengers in A , observe another aeroplane B moving perpendicular to direction of motion of A .Aeroplane B is actually moving in a direction 30^(@) north of east in the same horizontal plane as shown in the figure.Determine the velocity of B

A gas is enclosed in a container which is then placed on a fast moving train. The temprature of the gas

Choose the correct alternative :The effect of rotation on the effective value of acceleration due to gravity is greatest at the equator/poles.

The Bernoulli's equation is given by P+1/2 rho v^(2)+h rho g=k . Where P= pressure, rho = density, v= speed, h=height of the liquid column, g= acceleration due to gravity and k is constant. The dimensional formula for k is same as that for:

What will be the effect on the acceleration due to gravity at poles and at equator (a) If earth stops rotating ? (b) If rate of rotation of earth increases ?

A child pulls a rope attached to a stone with a force of 80N . The rope makes and angle of 40^(@) to the ground. (i) Calculate the effective value of the pull tending to move the stone along the ground. (ii) Calculate the force tending to lift the stone.
