In order to impress your neighbors and improve your vision in traffic jams, you decide to mount a cylindrical periscope 2.0 m hi

gh and 0.1 m in diameter on top of your car. You consult the literature and find that the drag coefficient (based on frontal area) is 1.1 for Re<200,000 (Re based on diameter) and drops to 0.35 for Re>200,000. Using this information, answer the three questions given. (HINT: make a sketch)The periscope's drag at your maximum speed of 75 mph is about:(A) 45 N(B) 4 N(C) 450 N(D) 5 N

What is the resultant force on one side of a 25cm diameter circular plate standing at the bottom of 3m of pool water?
Tom [10]

Answer:

F=1.47 KN

Explanation:

Given that

Diameter of plate = 25 cm

Height of pool h = 3 m

We know that force can be given as

F= P x A

P=ρ x g x h

Now by putting the values

P=1000 x 10 x 3

P= 30 KPa

A=\dfrac{\pi}{4}\times 0.25^2\ m^2

A=0.049\ m^2

F= 30 x 0.049 KN

F=1.47 KN

So the force on the plate will be 1.47 KN.
