Answer:

Massive destruction

Explanation:

If the asteroid collides with the ground, a massive volume of dust will be blasted into the environment. If it collides with water, the amount of water vapour in the atmosphere will rise. This would result in more rain, which would cause earthquakes and mudslides.

As the asteroid collided with the Earth, massive volumes of dust were ejected into to the atmosphere. The sun's light were stopped from entering the Earth's surface, which is terrible news for plants.

Suppose you were a heating engineer and you wished to consider a house as a dynamic system. Without a heater, the average temper

liq [111]

Answer:

As a heating engineer and considering a house as a dynamic system , and that without a heater, the average temperature in the house would vary over a 24-h period.

What might you consider for inputs, outputs, and state variables for a simple dynamic model?

State variables: according to the weather conditions of the area where the house was built:

State variable # 1: minimum temperture during a day in an specific season (*4);

State variable # 2: maximum temperature during the day, in an specific season (*4) as well;

State variable # 3: average temperature during the day in an specific season (*4).

That makes 16 state variables all of them in Centigrade degrees.

Input variables:

# 1: one degree over each of the state variables given.

# 2: one degree below each of the state variables, all of them in Centigrade degrees.

Output variables:

# 1 are the temperatures reached after adding one degree to each of the input variables.

# 2 are the temperatures reached after decreasing one degree, all of them in Centigrade degrees.

How would you expand your model so that it would predict temperatures in several rooms of the house?

I would add output variables in a "Y" system to predict temperatures in several rooms of the house.

How does the installation of a thermostatically controlled heater change your model?

It would change on the "Y" variables as they will get a control system designed for sensors to produce from some input variables to make the system respond.

Explanation:

State-determined system models using well defined physical systems is of highly interest to engineers.

The annual average of solar photovoltaic energy in Phoenix is 6,720

Dovator [93]

Answer:

The amount of money saved is $22,075.2

Explanation:

The solar voltaic energy in Phoenix, S $_E$ = 6,720 Wh/m²/day

The area on the roof available for solar panels, A = 500 m²

The percentage of the energy received by the solar panels converted into electricity, η = 15% = 0.15

The cost of electricity, C = $0.12/kWh

The number of days in a year, t = 365 days

Therefore, the maximum area covered by the solar panel = A = 500 m²

The total solar photovoltaic energy received by the solar panels, 'E', in a year is given as follows;

E = S $_E$ × A × t

By plugging in the values of the variables, we get;

E = 6,720 Wh/m²/day × 500 m² × 365 days = 1,226,400,000 Wh

The electrical energy generated, $E_e$ = η × E

∴ $E_e$ = 0.15 × 1,226,400,000 Wh = 183960000 Wh = 183,960 kWh

The amount of money saved = The cost of electricity generated = C × $E_e$

C × $E_e$ = $0.12/kWh × 183,960 kWh = $22,075.2

∴ The amount of money saved = C × $E_e$ = $22,075.2

) A flow is divided into two branches, with the pipe diameter and length the same for each branch. A 1/4-open gate valve is inst

Digiron [165]

Answer:

Va / Vb = 0.5934

Explanation:

First step is to determine total head losses at each pipe

at Pipe A

For 1/4 open gate valve head loss = 17 *Va^2 / 2g

elbow loss = 0.75 Va^2 / 2g

at Pipe B

For 1/3 closed ball valve head loss = 5.5 *Vb^2 / 2g

elbow loss = 0.75 * Vb^2 / 2g

Given that both pipes are parallel

17 *Va^2/2g + 0.75*Va^2 / 2g = 5.5 *Vb^2 / 2g + 0.75 * Vb^2 / 2g

∴ Va / Vb = 0.5934
