Answer:

ΔP = 1875 Pa, P₂ = P₁ - 1875

Explanation:

Let's use Bernoulli's equation, with the subscript 1 for the widest Mars and the subscript 2 for the narrowest part, suppose that the pipe is horizontal

P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ ρ v₂² + ρ g y₂

P₁ -P₂ = ½ ρ (v₂² - v₁²)

suppose the fluid is water

P₁ - P₂ = ½ 1000 (2² - 0.5²)

ΔP = 1875 Pa

this is the pressure difference between the two sections

the pressure in the narrowest section is

P₂ = P₁ - 1875

dmitriy555 [2]

The ration of the rms speed of 235uf6 to that of 238uf6 is 1.004.

The molecular mass of 235uf6 is 349, while that of 238uf6 is 352.

The rms speed is calculated as

v=√(3RT/m)

Thus the ratio rms speed of 235uf6 to 238uf6 is calculated as

r=√(352/349)=1.004

A classroom that normally contains 40 people is to be airconditioned with window air-conditioning units of 5-kW cooling capacity

oksano4ka [1.4K]

Answer:

About 2 units.

Explanation:

We assume that there is no heat dissipating instrument in the room

Total cooling load of the room is defined from the given below equation

$Q_{cooling}$ = $Q_{light}$ + $Q_{people}$ + $Q_{heat gain}$

where

$Q_{light}$ = 10*100 W =1 KW

$Q_{people}$ = 40*360 KJ/h= 4 KW

$Q_{heat gain}$ =15000KJ/h= 4.17 KW

$Q_{cooling}$ = 1+4+4.17=9.17 KW

the number of air conditioner unit is = $\frac{9.17}{5}$ =1.83

which is approximately 2 units

If i throw up an object up at 31 m/s, how long will it take to get to its highest point

Andreas93 [3]

Answer:

Explanation:

vf=vi+at

vf=31 m/s

vi=0 m/s

a=g=9.8 m/s2

t=?

vf-vi=at

vf-vi/a=t

t=vf-vi/a

t=31 m/s-0/9.8

t=3.16 s
