Kerala Kala Mandalam started in the year :
(ಹಿ) 1928 (B 1930 © 1932 (D) 1935

The rate of increase of pressure in liquid column towards vertically downward direction

must be equal to the of the fluid at that point.
(ಹಿ) Specific volume (B) Specific weight
(ಲ) Spedific gravity (D) None of the above

According to Pascals law, “The intensity of pressure at any point in a liquid at rest, is
_ வில்லி.
(5) € same (8) half (ಲ) one third (D) double

U - Tube manometers are used to measure of the liquid flowing through a pipe.
(ಹ) discharge (8) velocity (ಲ) density (D) pressure

Which of the following device is used to measure the discharge through open channel ?
(A) Venturimeter (B) Orifice meter (ಲ) Notches (D) Piezometer

The co-efficient of discharge {cd) of a venturimeter lies between the limits :
(ಹಿ) 0951099 ൫ 05085055 (9 085500 ೧) 0.60 ४० 0.66

In an open channel flow, If the flow characteristics, such as, velocity of flow, depth of flow,
rate of flow at any point do not change with respect to time, the flow is said to be

(A) Laminar flow (B) Uniformflow (ಲ) Steady flow (D) Turbulent flow

In a Centrifugal pump, the sum of Suction head and Delivery head is called :
(ಹ) Total head (8) Pressure head
(<) Manometric head (D) Static head

Following is an example of roto dynamic pump :
(A) Reciprocating pump (3) Centrifugal pump
(ಲ) Gear pump (D) Lobe pump

A Kaplan turbine is a
