At a certain location, wind is blowing steadily at 10 m/s. Determine the mechanical energy of air per unit mass and the power ge

Effectus [21]

Answer:

$X=3976.078202kW \approx 3976kW$

Explanation:

From the question we are told that

Wind speed $V_w=10m/s$

Turbine blade diameter $D=90m$

Air density $\tau=1.25kg/m^3$

Mechanical energy $K.E =0.05kJ/kg$

Generally the power generation potential of the wind turbine X is mathematically given as

$X=m'*K.E$

Where

$m'=\tau *\pi*D^2/4*V$

$m'=1.25 *\pi*90^2/4*10$

$m'=79521.56404kg/s \approx 79521.5kg/s$

Therefore

$X=m'*K.E$

$X=79521.56404*0.05$

$X=3976.078202kW \approx 3976kW$

$X=4.0MW$

The 25-mph zone is 150 yards long. How much time did the student save (in seconds) by speeding past the school

VikaD [51]

Answer:

Time = 12.27seconds

Explanation:

Given

Speed = 25miles/hour

Distance = 150 yards = 150(0.000568182)miles

Distance (in miles) = 0.0852273miles

Get the time

Speed = Distance/Time

Time = Distance/Speed

Time = 0.0852273/25

Time = 0.0034hours

Time = 0.0034 * 3600secs

Time = 12.27seconds

I NEED help A brief explanation on how TV uses radio waves.

Ipatiy [6.2K]

Radio waves have lower frequencies and longer wavelengths than microwaves. They are used to transmit television and radio programmes.Television uses higher frequencies than radio. A radio programme receiver does not need to be directly in view of the transmitter to receive programme signals.
