Answer:
i) 43.55 kg/s
ii) 40 m/s
iii) -199.32 KW
Explanation:
To resolve the above question we have to make some assumptions :
- mass flow through the system is constant
- The only interactions that are between the system and the surrounding are work and heat
- The fluid is uniform
i) first we have to determine the mass flow rate of the air
M = 
= 
---------- (1) hence M = 43.55 kg/s
ii) using this relationship : A1V1 = A2V2 hence V1 = (0.2/0.5) * 100 = 40m/s ( inlet velocity )
input this value into equation 1
iii) Next we will determine the power required to run compressor
attached below
power required = -199.32 KW ( this value indicates that there is power supplied )
The acceleration at points A, B and C are respectively; 960 mm²/s, 1600 mm²/s and 600 mm²/s
<h3>What is the acceleration?</h3>
The drum rolls without sliding and as such its' instantaneous center will lie at B. Thus;
V_d = V_c = 160 mm/s
Also, a_d = a_c = 600 mm²/s
Now, formula for velocity at A is;
V_a = r_ab * ω
where ω = 160/(100 - 60)
ω = 4 rad/s
V_a = 60 * 4
V_a = 240 mm/s
Acceleration at A = V_a²/r_ab
Acceleration at A = 240²/60 = 960 mm²/s
Now, V_b = 100 * 4 = 400 mm/s
Acceleration at B = 400²/100 = 1600 mm²/s

Answer:
Phase diagrams represent the relationship between temperature and the composition of phases present at equilibrium. An isomorphous system is one in which the solid has the same structure for all compositions. The phase diagram shown is the diagram for Cu-Ni, which is an isomorphous alloy system.
