One side of a plane wall is held at 200°C while the other side is exposed to a convective environment having T10°C and h 100 W/m

adelina 88 [10]

Answer:

$\frac{\dot Q}{A} = 151.33 W/m^2$

$T_c = 25.153°C$

Explanation:

Given data:

one side wall temperature 200°C

other side wall temperature 10°C

h = 100 W/m^2 °C

k = 2.6W/m °C

wall thickness L = 30 cm

we know that heat flux is given as

$\frac{\dot Q}{A} = \frac{ T_A - T\infty}{\frac{L}{K} + \frac{1}{h}}$

$\frac{\dot Q}{A} = \frac{ 20- 10} {\frac{0.30}{2.6} + \frac{1}{100}}$

$\frac{\dot Q}{A} = 151.33 W/m^2$

$1515.33 W/m^2 = \frac{ T_A - T_c}{\frac{L}{K}}$

solving for temperature for cold surface is given as

$T_c = -1515.33 \times \frac{0.3}{2.6} + 200$

$T_c = 25.153°C$

Oxygen decays to form nitrogen. 15 8 O → 15 7 N + 0 1 e This type of nuclear decay is called

Natasha2012 [34]

The type of nuclear decay in which Oxygen decays to form nitrogen is beta plus decay.

<h3>What is a beta plus decay?</h3>

A beta plus decay is a type of decay in which a proton in an element disintegrates to produce a neutron resulting in a decrease in the atomic number of the radioactive element.

In the given equation below:

$^{15}_{7}O \rightarrow ^{15}_{7}N + ^{0}_{1}e$

Oxygen decays to form nitrogen due to a decrease in atomic number.

This is an example of beta plus decay.

In conclusion, oxygen decays to form nitrogen beta plus decay.
