Danny enjoys studying transportation networks and systems. Which field of engineering should he pursue?

andre [41]

Answer:

Civil Engineering.

Explanation:

Civil Engineering is a field of engineering study that deals with professional practising in designing and developing infrastructures such as transport system and networks, buildings, etc.

<u>Civil engineering is regarded as the second--oldest form of engineering studies in the field of engineering.</u>

<u>A person who studies civil engineering is able to design and develop major projects in transportations system such as road construction, bridges, airports, tunnels, etc.</u>

So, Danny, who is interested in studying transporation networks and system should opt for studying civil engineering.

The temperature in a pressure cooker is 130 degree C while the water is boiling. Determine the pressure inside the cooker.

emmasim [6.3K]

Answer:

The pressure inside the cooker is 1.0804 atm.

Explanation:

Boiling occurs when the vapor pressure becomes equal to atmospheric pressure.

<u>For water, At standard conditions (Pressure = 1 atm) boiling occurs at 373.15 K.</u>

So, Standard conditions:

T₁ = 373.15 K

P₁ = 1 atm

Given ,

The water boils at Temperature = 130 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So, the temperature, T₂ = (130 + 273.15) K = 403.15 K

To find pressure inside the cooker (P₂) :

<u>Applying Amontons's Law as:</u>

$\frac {P_1}{T_1}=\frac {P_2}{T_2}$

So,

$P_2=\frac {P_1}{T_1} \times {T_2}$

$P_2=\frac {1 atm}{373.15 K} \times {403.15 K}$

$P_2=1.0804 atm$

<u>Thus, The pressure inside the cooker is 1.0804 atm.</u>

One kilogram of air as an ideal gas executes a Carnot power cycle having a thermal efficiency of 50%. The heat transfer to the a

Alexeev081 [22]

Answer:

(a) the maximum and minimum temperatures for the cycle in K;

Maximum temprature = T1 = 600.05K

Minimum temprature = 300.03K

(b) the pressure and volume at the beginning of the isothermal expansion in bar and m3 respectively;

Pressure (P4) = 0.67842 bar

Volume (V4) = 1.2693 $m^{3}$

(c) the work and heat transfer for each of the four processes in kJ.

$W_{4-1}$ = -215.25 kJ
