Question

The density of the object 1.21kg/m3

the diameter of the object .15m

the power fit of the trendline equation y=0.9226x^0.5737

Calculate the drag coefficient using these numbers

Answer #1

hello dear if you have any doubt please comment ...... thank you :)

Using a density of air to be 1.21kg/m3, the diameter of the
bottom part of the filter as 0.15m (assume circular cross-section),
and the power fit of your Trendline equation( y=.9226x^.5737 ,
calculate the drag coefficient.

Calculate the Reynold's number using a viscosity of air as
1.81E-05 kilograms/(meters-seconds), the density of air ( 1.21kg/m3
), the diameter as 0.15 m, and, from the data, 0.89 m/s.

A spherical object (50 cm diameter, c=0.46 kJ/kg*C, k = 42
W/m*C, density = 7800 kg/m3 ) is initially at a uniform temperature
of 450 C. It is suddenly placed in a constant temperature
environment of 100 C. The convection transfer coefficient is 500
W/m2*C. How long would it take for temperature in the center of the
sphere to cool down to 150 C? Note: Bi for a sphere is
(hD)/(6k).Suggestion: First calculate Biot number, then determine
if T is...

For a wind turbine with a rotor diameter of 43 meters, air
density of 1.125 kg/m3, and a wind velocity of 10 m/s, Wind power
density is calculated as follows:
A= Area= ¼ (π) D2 = ¼ (3.1416) (43)2 = 1451m2
Assuming 1m depth of the disk Volume = Area X Depth = 1451m2 X
1m = 1451m3
Mass = Density X Volume = 1.125 kg/m3 X 1451m3 = 1780 kg
WPD = Pwr/ A = ½ ρ V3 =...

The density of an object is about 400 kg/m3, and the density of
water is about 1000 kg/m3. A cubic block of the object one meter on
a side floats in water. Assuming that the lowest square face of the
cube is horizontal, the height of the block above the water line
is
0.9 m.
0.8 m.
0.5 m.
0.6 m.
0.1 m.

A spherical raindrop 3.1 mm in diameter falls through a vertical
distance of 3550 m. Take the cross-sectional area of a raindrop =
πr2, drag coefficient = 0.45, density
of water to be 1000 kg/m3,and density of air to be 1.2
kg/m3.
(a) Calculate the speed a spherical raindrop would achieve
falling from 3550 m in the absence of air drag.
(b) What would its speed be at the end of 3550 m when there is
air drag?

An object of mass M and density ρ released from rest while under
water. The object feels a viscous drag from the water with a drag
constant K. What is the terminal speed of the ball?
free body and what laws
What do you expect to happen to the terminal velocity as
the density of the ball approaches the density of the
water?
A. As the density of the object approaches the density of the
water, the terminal speed increases...

A hollow steel sphere (the density of steel is 7820
kg/m3) with an internal diameter of 10 cm and a
thickness of 7mm is attached to a wooden cylinder (the wood has a
density of 900 kg/m3) with a length 50 cm and a diameter
of 20 cm. The inside of the sphere is filled with a fluid. If the
system is neutrally buoyant in water with a density of 998.2
kg/m3, determine the density of the fluid inside the...

An object with a density of 681.0 kg/m3 and a mass of 1831.0 kg
