The density of the atmosphere varies drastically with height, but you can use an average density from sea floor to the space in order to calculate its height. If we approximate this average density to be = 1 Kg/m³, what would be height of the atmosphere? HINT: Since the atmosphere is a fluid (in gas form), you can use the hydrostatic pressure formula (P pgh), just solve for h and use P = 1 atm. BTW, this is how the edge of space is defined, if you make it pass the height of the atmosphere you have reached space :)

Calculate the pressure difference, in pascals, between levels C and A, ΔP = PC - PA, for ρ = 0.93×103 kg/m3 and d = 2 cm

The atmospheric pressure at the sea level is 500,000 N /m ^2 please estimate the total mass (in the unit Kg) of the earths atmospheric above the sea level of an area of 1m^2? Write answer as a whole number

The atmospheric pressure on an object decreases as altitude increases. If a is the height (in km) above sea level, then the pressure P(a) (in mmHg) is approximated by P(a)=760e-0.13a. Determine the atmospheric pressure at 7.176 km. Round to the nearest whole unit.

A smoking room is to accommodate 50 smokers. The fresh air requirement for smoking areas is specified to be 40 L/s per person. The air velocity in the ventilation duct is 8 m/s. Determine: b) The diameter of the ventilation duct in [cm] SOLUTION

garbage worker tears the arm off a droid. he throws it down a garbage chute and it lands in trash filled with nasty smelly liquids. the overall density is 840kg/m^3. if the arm has a desnity of 5460kg/m^3 and is a cylinder with the volume of 0.0330m^3 what is the buyoncy force in newtons acting on the arm?

A mercury manometer (r = 13,600 kg/m3) is connectedto an air duct to measure the pressure inside. Thedifference in the manometer levels is 15 mm, and the atmosphericpressure is 100 kPa. (a) Judging from Fig. P2–50,determine if the pressure in the duct is above or below theatmospheric pressure. (b) Determine the absolute pressure inthe duct.

Water is discharged from a pipeline at a velocity v given by v=1340*squarerootof p, where p is the pressure in (psi). If the water pressure is changing at a rate of 0.47 psi/second, find the acceleration (dv/dt) of the water when p=20 psi. Round the answer to two decimal places. dv/dt=
