Answer:

Both

Explanation:

Because of water, fuel does not burn completely. This brings about water fumes that are white in color and looks like white smoke. If engine is cold and water is heating, it leads to steam formation like water vapor. The white times are because of not firing properly in the heated engine. Technician A is right.

Blue fine is caused by this scoring. It is also caused by dirty oil. Technician b is right too

Cual es el impacto medioambiental del mortero?
ddd [48]

Explanation:

La industria del acero desecha gran cantidad de polvos, los que acopiados al aire libre, sobre el suelo y sometidos a ¡a acción de los agentes climáticos, contaminan el medio ambiente. El propósito del presente trabajo es evaluar el impacto ambiental que produce la incorporación de polvos de acería a matrices de cemento portland, sometidas a condiciones de humedad, presión y temperatura. Se caracterizó químicamente el material de desecho de una acería de Argentina, para identificar los elementos presentes. Por difractometría de rayos X (XRD) se determinaron las estructuras de las sustancias y su grado de oxidación. Se utilizó SEM-EDAX con el propósito de observar forma, tamaño y composición química de las partículas. Se elaboraron diferentes morteros de cemento Portland y se incorporó este material en diferentes porcentajes. Se moldearon probetas normalizadas para realizar ensayos mecánicos, de lixiviación y estudios petrográficos. Se analizó la composición química del agua de curado de las probetas y del líquido obtenido en ensayos de lixiviación. Los resultados permitieron identificar y cuantificar los elementos peligrosos que pueden se incorporados al ambiente y sugerir medidas de prevención.

What color is a board sternlight
alukav5142 [94]

We can infer and logically deduce that the color of a boat's sternlight is white.

<h3>What is a sternlight?</h3>

A sternlight can be defined as a white light that is designed and developed to be placed as closely as possible and practical with the stern shining continuously (constantly).

By default, a sternlight is typically affixed to the boat in such a way that the light will shine out at an angle of 135 degrees (135°) from the back of the boat.

In this context, we can infer and logically deduce that the color of a boat's sternlight is white and it avails sailors and other persons the opportunity of determining and knowing the direction that a boat (vessel) is moving.

An uninsulated, thin-walled pipe of 100-mm diameter is used to transport water to equipment that operates outdoors and uses the
Viefleur [7K]

Answer:

4.6 mm

Explanation:

Given data includes:

thin-walled pipe diameter = 100-mm =0.1 m

Temperature of pipe T_p = -15° C = (-15 +273)K =258 K

Temperature of water T_w = 3° C = (3 + 273)K = 276 K

Temperature of ice T_i = 0° C = (0 +273)K =273 K

Thermal conductivity (k) from the ice table = 1.94 W/m.K  ;  R = 0.05

convection coefficient Lh_l =2000 W/m².K

The energy balance can be expressed as:

q_{conduction} =q_{convention}

where;

q_{conduction} = \frac{2\pi LK(T_i-T_p)}{In(R/r)}       -------------   equation (1)

q_{convention} = \pi DLh_l(T_w-T_i)  ------------ equation(2)

Equating both equation (1) and (2); we have;

\frac{2\pi LK(T_i-T_p)}{In(R/r)} = \pi DLh_l(T_w-T_i)

Replacing the given data; we have:

\frac{2\pi (1)(1.94)(273-258)}{In(0.05/r)} = \pi (0.1)*2000(276-273)

\frac{182.84}{In(\frac{0.05}{r}) } = 1884.96

In(\frac{0.05}{r})*1884.96 = 182.84

In(\frac{0.05}{r}) = \frac{182.84}{1884.96}

In(\frac{0.05}{r}) =0.0970

\frac {0.05}{r} =e^{0.0970}

\frac {0.05}{r} =1.102

r=\frac{0.05}{1.102}

r = 0.0454

The thickness (t) of the ice layer can now be calculated as:

t = (R - r)

t = (0.05 - 0.0454)

t = 0.0046 m

t = 4.6 mm
