Answer:
rate of heat transfer through wall per unit area of the wall is 102 W/m²
Explanation:
We know that the thermal resistance of a composite wall withe two layers, is equal to the sum of the resistance of each wall:
R = R1 + R2
where,
R = total resistance of composite wall
R1 = resistance of layer A = LA/KA(Area) = (0.06 m)/(0.7 W/m. °C)(Area)
R1 = (0.08571 W/°C)/(Area)
R2 = resistance of layer B = LB/KB(Area) = (0.03 m)/(0.25 W/m. °C)(Area)
R2 = (0.12 W/°C)/(Area)
therefore,
R = (0.08571 W/°C)/(Area) + (0.12 W/°C)/(Area m²)
R = (0.20571 W/°C)/(Area)
Now, we know that:
R = ΔT/Q
where,
R = total thermal resistance = (0.20571 W/°C)/(Area m²)
ΔT = Temperature drop = 21° C
Q = Heat transfer
Therefore,
(0.20571 W/°C)/(Area m²) = 21°C/Q
Q/Area m² = q = 102 W/m²
<u>q = 102 W/m²</u>
Answer:
- the resolution in volts is 0.1526 mV
- the resolution in ⁰C is 1.526⁰C
Explanation:
Given;
the length of bit, n= 16
full-scale range = 10V
Resolution = (full-scale range)/2ⁿ
Resolution = (10V)/2¹⁶
Resolution = 10 V/65536
Resolution = 0.1526 mV
Given;
sensor having a sensitivity of 0.1 mV/⁰C
The resolution in ⁰C is calculated as follows:
Therefore, the resolution in ⁰C is 1.526⁰C
Answer:
Power of a machine is defined as its rate of doing work. It is the rate of transfer of energy. The power of a machine is said to be one watt if it can work at the rate of one joule in one second.
