Refrigerant 134a enters a well-insulated nozzle at 200 lbf/in.2, 200°F, with a velocity of 120 ft/s and exits at 50 lbf/in.2 wit
riadik2000 [5.3K]

Answer:

x = 0.75801 = 75.801%

T_2 = 72..78 degree F

Explanation:

From superheated R 134 a properties table

At 200 lb/in^2 and 200 degree F

h_1 = 138.99 Btu/lbm

steady flow energy equation is givena s

h_1 + \frac{v_1^2}{2}  = h_2 + \frac{v_2^2}{2}

138.99 + \frac{120^2}{2\times 25037} = h_2 + \frac{1500^2}{2 \times 25037}

h_2 = 94.344 Btu/lbm

At 90 lb/in2 Tsat = 72.78 degree F

h_f = 35.715 Btu/lbm

hfg  = 77.345 Btu/lbm

h = hf + x hfg

94.344 = 35.715+ x \times 77.345

solving for x we get

x = 0.75801 = 75.801%

T_2 = 72..78 degree F

What is force <br>what is the importance of force​
frutty [35]

Force is the ability to cause masses to accelerate.

Without force, you could not make stuff accelerate.

If something was moving, you could not make it speed up, slow down, stop, or go in a different direction.

If a thing was not moving, you could not make it move at all.

Grace pushes her foot against the wall with a force of 35 N while she stands
Airida [17]

Answer:

The correct answer is B. 0.64 m/s²

Explanation:

According to the Newton's Second law of motion acceleration of an object by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force.

Mathematically,

                           F ∝ a

                           F = ma

Given data:

Force = F = 35 N

Mass = m = 55 kg

acceleration = a = ?

                           F = ma

                           a = F/m

                           a = 35/55

                          a = 0.64 m/s²
