The approximate average power output is mathematically given as
P=1097.6w
<h3>
What is the approximate average power output?</h3>
Question Parameters:
Iowa with a 10 m2 swept area and 50 m hub height
Assume 80% of the Betz limit, 80% conversion efficiency, and air density of 1.0 kg/m3. Wind speed is 7 m/s2
Generally, the equation for the average output power is mathematically given as
Where
B= Benz coefficient
n=0.8
Therefore
P=0.5*1*0.8*10*7^3*0.8
P=1097.6w

What is the approximate average power output of a well-designed modern turbine in Des Moines, Iowa with a 10 m2 swept area and 50 m hub height? Assume 80% of the Betz limit, 80% conversion efficiency, and air density of 1.0 kg/m3. Wind speed is 7 m/s2
Answer: c.An accumulator is not used in a system with a receiver/dryer
Explanation:
In a refrigeration system, a condenser is used to transfer heat and this occurs from the refrigerant to the air or water.
Then, the refrigerant then condenses to liquid when the hear has been transferred.
We should note that the condenser is normally mounted in front of the radiator. The receiver/dryer is a storage tank for the liquid refrigerant from the condenser.
The statement that an accumulator is not used in a system with a receiver/dryer is not true. This is because, the accumulator gives protection to the compressor which helps to prevent the failure of the compressor.
Therefore, the answer is C.
Answer: A
Explanation: because it shows 10 ahead
