Consider a very long fin of diameter 1.6 cm made of a material with thermal conductivity 274 W/m-K. The surface that the fin is attached to is 102C. The ambient air around the fin is at 16C and the heat transfer coefficient is 23 W/m^2-K. Required:
Determine the heat transfer rate from the fin and the increase in the rate of heat transfer per square meter surface area.

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
