Diphenhydramine (Benadryl) is the most common first-generation antihistamine found in OTC sleep aids, whether used alone or in combination with pain relievers, including acetaminophen (eg, Tylenol PM), ibuprofen (eg, Advil PM), and aspirin. Other sleep aids often contain the antihistamine doxylamine (eg, Unisom).
The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. An average onshore wind turbine with a capacity of 2.5â3 MW can produce more than 6 million kWh in a year â enough to supply 1,500 average EU households with electricity. An average offshore wind turbine of 3.6 MW can power more than 3,312 average EU households.
At the optimum wind speed of 25-35 mph, the blades will rotate at 14 rpm. That gives them a speed of 105 mph at the tip. How much electricity do they produce? Each turbine produces about 2,000,000 kilowatt hours (kwh) per year, enough energy to power as many as 500 typical homes at 12,000 kwh per year.How strong do the winds have to blow for the blades to rotate? Wind turbines start operating at wind speeds of around 8 mph and reach a maximum power output at around 33 mph.When there is not enough wind to turn the blades, or when there is too much wind the turbines shut down.ow strong do the winds have to blow for the blades to rotate?
