Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:
(b) The frequency of a wave is inversely proportional to its period:
(c) The wavelength is the distance between two successive crests, so:
(d) The speed of a wave is defined as:
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°.
