Water is flowing through a horizontal pipe of varying cross-section. If the pressure of water equals 2 cm of mercury, where the velocity of the flow is , what is the pressure at another point, where the velocity of flow is ?
View answer and explanation
Correct option: B
1.88 cm of Hg
Option B is correct because it is calculated by applying Bernoulli's equation and converting pressure units to cm of Hg.

With the increase in temperature viscosity of a liquid -
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.
Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.
In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
on As the temperature of a liquid is raised, the coefficient of viscosity A horizontal pipe of cross-sectional diameter 5 cm carries water at velocity of . The pipe is connected to a smaller pipe with a cross-sectional diameter 4 cm. the velocity of water through the smaller pipe is If two soap bubble of different radii are connected by a tube
