Answer: by giving special shapes called streamlined shape to the objects
Explanation:
Answer:
Average velocity of water flow through the pipe = 3.98 m/s
Explanation:
Diameter of pipe = 20 mm
Discharge = 75 L/min
We know that
Discharge = Area x Velocity
Discharge = 75 L/min
Substituting
Average velocity of water flow through the pipe = 3.98 m/s
kess dense material comes up. glycerin dencity= 37.8 / 30
syrup density = 80 / 60 so glycerin is less dense and comes up
You can do this if you have a working knowledge of calculus.
You need to model the acceleration as a function of time, ie obtain a function a(t) that gives acceleration a for any time t.
Using the fundamental theorem of calculus, you should integrate a(t) from t=0 to a variable value of time t. This should get you an expression in terms of t.
Now set this expression equal to the difference of the final and initial velocity, v-u, and solve for t.
