Answer:
Heat flux is 20 W/m^2
Explanation:
Heat flux (Q) is computed as
where h is heat transfer coefficient and ΔT is the difference between body's temperature
From the interior air to the inner wall
From the the outer wall to the exterior air
The wall is under steady-state condition because heat flux is constant
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>
So,
<u>Thus, The pressure inside the cooker is 1.0804 atm.</u>
