What is the power required to maintain an automobile at a Cruising speed of 60 mph on a level road?
10 to 20 horsepower
One reason is that a car needs a fair amount of power to make its way down the road. At 60 mph, a typical car needs 10 to 20 horsepower simply to maintain its speed. That energy level is needed to overcome wind resistance and the rolling resistance in the tires.
How much horsepower do you need to go 50 mph?
In any case I calculated from this rather crude test that 50 MPH should be attainable with less than 12 HP. Testing for 30 MPH should be much safer if you can just find a very long hill with perhaps a one degree slope, no wind and no traffic.
At what speed does the Prius switch to gas?
15 miles per hour
In general, a Prius switches from battery to gas when the car reaches speeds of 15 miles per hour or more. For all your hybrid vehicle repair needs, contact the hybrid specialists at Luscious Garage in San Francisco, California by giving them a call at 415-213-2336 today!
How much energy do you get from speed?
When traveling on level roads at constant speed, most passenger cars need only about 20 hp or so to overcome rolling friction and air drag. (More power would be needed, obviously, if you were carrying a door on top of your car, with the flat side perpendicular to the line of travel.
How much power is required to move a car?
If it was a very compact electric vehicle with steel wheels on a level steel track with no wind you might be able to do it with a 1000 watts. On the other hand if you had a 4 wheel drive van with soft tires climbing a sand dune into a heavy wind you might take 50,000 watts.
What is meant by power requirement of a vehicle?
The power output requirement can be determined from the drag force given above and the vehicle velocity. P = FDV. Given the mass of a vehicle and its frontal surface area, a plot can be drawn showing the power requirements for a range of speeds. The Power Requirement Applet plots this relationship.
How fast is 60 horsepower?
16′ aluminum boats are popular and a 60-hp engine will typically propel them from 25 mph to 30 mph top speed, depending on load.
How much horsepower does a duck power have?
It turns out that it is quite feasible to convert from horsepower to duckpower using a simple formula based on the animals’ average mass. You’re looking at about 131.2 ducks to 1 horse, so simply multiply your horsepower figure by that, and you get the duckpower number.
How far can a Toyota Prius go on battery power?
25 miles
An 8.8-kWh battery pack is thoughtfully placed in the rear of the vehicle. The battery has been optimized for daily commutes, providing more interior room for your rear passengers and an EPA-estimated 25 miles of driving range in EV Mode.
Does a Prius run on electricity?
The Toyota Prius is a parallel hybrid; this means it has a gasoline engine and electric motor that are separate from one another. Further, each can run on its own. Toyota designed the Prius so that it would utilize electric power (which it stores in the battery) instead of gasoline power whenever possible.
How is electrical power calculated?
Electrical power is the product of voltage and current. P=VXI. P = V X I .
How do I calculate power?
Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.
