The gage pressure measured as 2.2 atm, the absolute pressure of gas is 3.2 bar. Please determine the local atmospheric pressure

LiRa [457]

Answer:

$97.085\ \text{kPa}$

Explanation:

$P_{g}$ = Gauge pressure = 2.2 atm = $2.2\times 101325=222915\ \text{Pa}$

$P_{abs}$ = Absolute pressure = $3.2\ \text{bar}=3.2\times 10^5\ \text{Pa}$

$P_{atm}$ = Local atmospheric pressure

Absolute pressure is given by

$P_{abs}=P_{atm}+P_g\\\Rightarrow P_{atm}=P_{abs}-P_g\\\Rightarrow P_{atm}=3.2\times 10^5-222915\\\Rightarrow P_{atm}=97085\ \text{Pa}=97.085\ \text{kPa}$

The local atmospheric pressure is $97.085\ \text{kPa}$ .

In using the drag coefficient care needs to be taken to use the correct area when determining the drag force. What is a typical

stealth61 [152]

Answer:

Explanation:

We know that Drag force $F_D$

$F_D=\dfrac{1}{2}C_D\rho AV^2$

Where

$C_D$ is the drag force constant.

A is the projected area.

V is the velocity.

ρ is the density of fluid.

Form the above expression of drag force we can say that drag force depends on the area .So We should need to take care of correct are before finding drag force on body.

Example:

When we place our hand out of the window in a moving car ,we feel a force in the opposite direction and feel like some one trying to pull our hand .This pulling force is nothing but it is drag force.
