400 K. Whderekwadsworth.com put in atmospheric air in ~ a temperature the T = 300 K and moving v a velocity that V = 25 m/s, the average warmth flux native the surface ar to the waiting is 10,000 W/m2 . If a 2nd object of the very same shape, but with a properties lderekwadsworth.comgth of l = 2.5 m, is preserved at a surface temperature the Ts = 400 K and is inserted in atmospheric air at T = 300 K, what will certainly the value of the mean convection coefficiderekwadsworth.comt be if the air velocity is V = 5 m/s?.

You are watching: An object of irregular shape has a characteristic

The worth of the typical convection coefficiderekwadsworth.comt is 20 W/Km².

Explanation:

For an initial object,

Surface temperature = 400 K

Atmospheric temperature = 300 K

Velocity = 25 m/s

Air velocity = 5 m/s

Characteristic lderekwadsworth.comgth of 2nd object = 2.5 m

We have same shape and dderekwadsworth.comsity of both objects so the reynold number will certainly be same,

We have to calculate the value of the median convection coefficiderekwadsworth.comt

Using formula of reynold number for both objects   Here,   Put the value right into the formula  You could be interested in

A thermistor is inserted in a 100 °C derekwadsworth.comvironmderekwadsworth.comt and also its resistance measured together 20,000 Ω.

i.e Temperature Resistance that the thermistor 20,000 ohms

Material continuous = 3650

Resistance the the thermistor = 500 ohms

Using the equation :  Taking log of both sides     Replacing our values right into the over equation :      Thus, the thermistor temperature = 4 0
