Answer:
1.75 kW
$0.137 kWh
4.61 kW
$3.16 therm
Explanation:
Utilized power input of the burner is
P(ui) = total power input * efficiency
P(ui) = 2400 W * 0.73
P(ui) = 1752 W or 1.75 kW
Unit cost of utilized energy is
C(ui) = Unit cost of electricity/efficiency
C(ui) = $0.1 / 0.73 kWh
C(ui) = $0.137 kWh
Power input to the gas burner is
P(gi) = Utilized power input of the burner / efficiency of the burner
P(gi) = 1.75 / 0.38
P(gi) = 4.61 kW
Unit cost of utilized energy is
C(gi) = Unit cost of gas /efficiency
C(gi) = $1.2 / 0.38 kWh
C(gi) = $3.16 therm

Answer:
15.65 MPa 150 times of human body internal pressure
Explanation:
Given:
- Depth of the ocean for offshore drilling d = 1 mile
Find:
Determine the pressure at that location
What would happen to an unprotected, exposed person at that depth?
Solution:
- The pressure at a certain depth of a fluid can be calculated with:
P = p_w*g*d
Where, P is the pressure , p_w is the density of water ( 997 kg / m^3 ).
- Hence @ d = 1.0 mile = 1.6 km = 1600 m:
P = 997*9.81*1600
P = 15.65 MPa
- Whereas the pressure inside a human body is 101 KPa, Pressure under ocean @ 1 mile of depth is 150 times in magnitude, enough to crush the human body!
Answer:
W = 166.35 KJ
Explanation:
P₁ = 600 KPa
V₁ = 0.4 m³
V₂ = 0.2 m³
T = 300 K
W = ?
We can find the solution from the standard relation for work in an isothermal process
W = -n*R*T*Ln (Vf / Vi)
We know that
n*R*T = P*V ⇒ P₁*V₁ = P₂*V₂ = n*R*T = 600 *0.4 = 240
Now, we use the equation
W = -n*R*T*Ln (Vf / Vi) = - P₁*V₁*Ln (Vf / Vi)
⇒ W = -240*Ln (0.2 / 0.4) = 166.35 KJ
An American architect whose principles of building included consonance with the landscape was:
<h3>Who was Frank Lloyd Wright?</h3>
Frank Lloyd Wright was an American architect who lived between 1867 to 1959. One of the notable features of his prairie houses was their ability to rhyme with the Chicago landscape.
The Unity Park in Illinois and the Hillside Home School in Wisconsin were some structures that he erected.
