Answer:
The temperature change per compression stroke is 32.48°.
Explanation:
Given that,
Angular frequency = 150 rpm
Stroke = 2.00 mol
Initial temperature = 390 K
Supplied power = -7.9 kW
Rate of heat = -1.1 kW
We need to calculate the time for compressor
Using formula of compression
Put the value into the formula
We need to calculate the rate of internal energy
Using first law of thermodynamics
Put the value into the formula
We need to calculate the temperature change per compression stroke
Using formula of rate of internal energy
Put the value into the formula
Hence, The temperature change per compression stroke is 32.48°.
Answer:
8.40 m/s
Explanation:
Slope of the plot is 0.119
Slope of a plot is given by the change in y direction divided by the change in x direction
Here, the y axis represents inverse wavelength and the x axis represents frequency.
f = Frequency (Hz, assumed)
v = Phase velocity (m/s, assumed)
λ = Wavelength (m, assumed)
So, slope
Now,
The speed of sound travelling in the tube is 8.40 m/s
