Answer:
Explanation:
Given:
- temperature of skin,
- initial temperature of steam vapour,
- latent heat of steam,
- mass of steam,
- specific heat of water,
- final temperature,
<em>Assuming that no heat is lost in the surrounding.</em>
<u>We know:</u>
<u>Now the total heat given by the steam to form water at the given conditions:</u>
..............................(1)
where:
latent heat given out by vapour to form water of 100°C
heat given by water of 100°C to come at 34°C.
putting respective values in eq. (1)
is the heat transferred to the skin.
The fundamental frequency of the tube is 0.240 m long, by taking air temperature to be C is 367.42 Hz.
A standing wave is basically a superposition of two waves propagating opposite to each other having equal amplitude. This is the propagation in a tube.
The fundamental frequency in the tube is given by
where,
Since, T=37+273 K = 310 K
v = 331 m/s
Using this, we get:
Hence, the fundamental frequency is 367.42 Hz.
