A mass of 0.01 kg of steam at a quality of 0.9 is contained in the cylinder as shown in Figure 1 below. The spring just touches the top of the piston. Heat is then added until the air expanded, and the spring is compressed by 15.7 cm. Calculate the final temperature of the steam in this cylinder. Sketch the process on a P-v and T-v diagrams with respect to saturation lines K = 50 kN/m 160 kg 20 cm Figure 1 Piston cylinder with spring
True. it’s at rest which means it’s not moving so there’s no acceleration
Answer: 69.8 degree
Explanation:
F*cos(theta)
is your pushing force projected along the x axis and
-F*0.368*sin(theta)
is the friction force generated by the pressure downwards
when F cos(theta) = F*0.368*sin(theta)
the box wont move no matter how large F is, because you are adding no net force along the x-axis
so sin(theta)/cos(theta) = 1/0.368
tan^-1(1/0.368) = theta
theta = 69.8 degrees
I think the correct answer from the choices listed above is option C. The scatter plot above shows the relationship between the pressure and volume of a gas in which the <span>pressure of a gas increases as its volume decreases. However, they are not linearly related. Hope this answers the question.</span>
