The Pitot tube is used to measure.

Detailed Solution for APSC JE CE Paper 2 Mock Test - 6 - Question 7
Pitot tube: It is a simple device used for measuring the velocity of flow. The basic principle used in this device is that if the speed of flow at a particular pit is reduced to zero, which is known as stagnation point, the pressure there is increased due to the conversion of the kinetic energy into pressure energy, and by measuring the increase in the the pressure energy at this point, the velocity of flow may be determined.

Quicksand is a-

Detailed Solution for APSC JE CE Paper 2 Mock Test - 6 - Question 8
Quick Sand condition If the seepage pressure becomes equal to the pressure due to the submerged weight of the soil, then evidently, the effective pressure is reduced to zero. In such a limiting case, the Cohesionless soil loses all its shear strength, and the soil particles will tend to move up in the direction of flow. This phenomenon of the lifting of soil particles is called the quick condition or boiling condition, or quick sand. The hydraulic gradient corresponding to this situation (Just starting) is called critical hydraulic gradient ((ic)) Where,
