Shielded metal arc welding (SMAW), also known as manual metal arc welding, is a manual arc welding process that uses a consumable and protected electrode. As the electrode melts, a cover that protects the electrode melts and protects the weld area from oxygen and other atmospheric gases

a. The maximum thickness of the copper nozzle is 3.3 mm

b. The maximum thickness of the steel nozzle is 0.054 mm

The question has to do with heat transfer

Heat transfer is the movement of heat energy from one body to anotrher.

Since the rate of heat loss by the gas equal rate of heat gain by the metal.

The rate of heat loss by gas is P = -hA(T - T') where

The rate of heat gain by metal is given by P' = kA(T - T")/t where

Since P = P', we have that

-hA(T - T') =  kA(T - T")/t

Making t subject of the formula, we have

t = -k(T - T")/h(T - T')

Given that for copper

Substituting the values of the variables into t, we have

t = -k(T - T")/h(T - T')

t = -378 W/m-K(540°C - 150°C)/[2 × 10⁴ W/m²-K(540°C - 2750°C)]

t = -378 W/m-K(390°C)/[2 × 10⁴ W/m²-K(-2210°C)]

t = 147420 W/m/4420 × 10⁴ W/m²

t = 147420 W/m/44200000 W/m²

t = 0.0033 m

t = 3.3 mm

So, the maximum thickness of the copper nozzle is 10.71 cm

Given that for steel

Substituting the values of the variables into t, we have

t = -k(T - T")/h(T - T')

t = -23.2 W/m-K(980°C - 150°C)/[2 × 10⁴ W/m²-K(980°C - 2750°C)]

t = -23.2 W/m-K(830°C)/[2 × 10⁴ W/m²-K(-1770°C)]

t = 19256 W/m/3540 × 10⁴ W/m²

t = 19256 W/m/35400000 W/m²

t = 0.0000544 m

t = 0.0544 mm

t ≅ 0.054 mm

So, the maximum thickness of the steel nozzle is 0.054 mm

Explanation:

By using a forward-inclined half-moon torch position, stopping momentarily at each end of the weld pool

Adjusting welding parameters, using appropriate electrode size, and maintaining proper torch angle can prevent undercutting in horizontal

welding of an inside corner.

We have,

When an inside corner is being welded in the horizontal position, undercutting can be decreased or prevented by adjusting the welding parameters, such as:

- Controlling Welding Parameters:

Adjusting the welding parameters is crucial in preventing undercutting.

It involves regulating the welding current, voltage, and travel speed.

- Selecting Appropriate Electrode Size:

Choosing the right electrode size is essential to control the heat generated during the welding process.

Smaller electrode diameters generally provide lower heat input, which can help prevent undercutting.

- Maintaining Proper Torch Angle and Manipulation Techniques:

Keeping the correct torch angle during welding is crucial to control the weld pool and metal deposition.

- reducing the welding current and travel speed

- using the appropriate electrode size

- maintaining proper torch angle and manipulation techniques.

Thus,

The design speed was used for the freeway exit ramp is 11 mph.

The design speed used in the exit ramp is calculated as follows;

f = v²/15R - 0.01e

where;

v = ωr

v = (θ/t) r

θ = 90⁰ = 1.57 rad

v = (1.57 x 19.4)/2.5 s

v = 12.18 ft/s = 8.3 mph

f = v²/15R - 0.01e

let the maximum superelevation, e = 1%

f = (8.3)²/(15 x 19.4) - 0.01

f = 0.22

0.22 is less than value of f which is 0.4

f = (10)²/(15 x 19.4) - 0.01

f = 0.33

0.33 is less than 0.4

f = (11)²/(15 x 19.4) - 0.01

f = 0.4

When a room becomes so hot that everything in it ignites simultaneously it is termed a flashover.

In a confined space, a flashover occurs when the majority of the directly exposed flammable material ignites almost simultaneously. Certain organic compounds go through thermal decomposition when heated and emit combustible gases as a result.

Every flammable surface exposed to thermal radiation in a compartment or confined space ignites quickly and simultaneously during a flashover, a thermally driven event. For typical combustibles, flashover typically happens when the upper section of the compartment achieves a temperature of about 1,100 °F.

Flashover circumstances are more likely to occur in buildings with hidden compartments, lower ceiling heights, room partitions, and energy-efficient or hurricane windows.

Therefore, the sudden ignition of everything in the room is called a flashover.
