List of top Physics Questions on Fluid Mechanics asked in AP EAMCET

Water flows from a tap of diameter 1.5 cm with velocity \( 7.5 \times 10^{-5} \, \text{m}^{3}\text{s}^{-1} \). The coefficient of viscosity of water is \( 10^{-3} \) Pas. The flow is:
Two cylindrical vessels A and B of different areas of cross-section kept on the same horizontal plane are filled with water to the same height. If the volume of water in vessel A is 3 times the volume of water in vessel B, then the ratio of the pressures at the bottom of the vessels A and B is:
Water is flowing in a streamline manner in a horizontal pipe. If the pressure at a point where cross-sectional area is \( 10 \) cm\(^2\) and velocity \( 1 \) m/s is \( 2000 \) Pa, then the pressure of water at another point where the cross-sectional area is \( 5 \) cm\(^2\) is:
Statement (A): When the temperature increases the viscosity of gases increases and the viscosity of liquids decreases.
Statement (B): Water does not wet an oily glass because cohesive force of oil is less than that of water.
Statement (C): A liquid will wet a surface of a solid if the angle of contact is greater than \(90^\circ\).
Choose the correct option.
