Answer 1

ANS;

1) Measuring viscosity is an effective way of determining the state (properties of matter) or fluidity of a liquid or gas. It plays an important role in the quality control and various research and development stages in lab, process and research environments as well as a wide range of industries and applications including Food, Chemical, Pharmaceutical, Petrochemical, Cosmetics, Paint, Ink, Coatings, Oil and Automotives. In Civil Engineer it plays vital role in determining parameters in Dams and Hydraulics.

2) Since the forces of water on a dam are hydrostatic forces, they vary linearly with depth. The total force on the dam is then the integral of the pressure multiplied by the width of the dam as a function of the depth. The hydrostatic force and tipping moment on the dam about some point can be computed from the total force and center of pressure location relative to the point of interest.

3) Follwing Applications are considered,

a) Floating objects (Ships and Boats): To study ability of Ships and Boats to Float on Water.

b) Submarines: To study ability of Submarines to Float on water during accident situations.

c) Helium Balloons and Airships: To study ability of Balloons and Airships to flow in air.

4) Bernoullis Experiment

a) Airflight: The main way that Bernoulli's principle works in air flight has to do with the architecture of the wings of the plane. In an airplane wing, the top of the wing is soomewhat curved, while the bottom of the wing is totally flat. While in the sky, air travels across both the top and the bottom concurrently. Because both the top part and the bottom part of the plane are designed differently, this allows for the air on the bottom to move slower, which creates more pressure on the bottom, and allows for the air on the top to move faster, which creates less pressure.

b) Baseball: Baseball Baseball is an example of where Bernoulli's principle is very visible in everyday life, but rarely do most people actually take note of it. One example in baseball is in the case of the curve ball. The entire pitch works because of Bernoulli's principle. Since the stitches of the ball actually form a curve, it is necessary for the pitcher to grip the seams of the baseball. The reason as to why this is a necessity is that by gripping the baseball this way, the pitcher can make the ball spin.

c) Venturimeter: The flow speed of a fluid can be measured using a device called venturimeter. It works on Bernoulli’s principle.

I don't have answers for the remaining two experiments.
