What is the kinetic energy of one cubic foot of water traveling at 5 mph?

You must first determine the mass of the water, and you must also do some unit conversion. Since you know the volume of water, you must first determine its mass. One cubic foot of water weighs about 62.4 pounds (pound-force, lbf). But that's weight, not mass. What is the mass of 62.4 lbf of water? Since m = W/g, we get 62.3/32.2 = 1.93 slugs. (Note that the density of water varies with temperature, so the weight of a cubic foot of water will vary somewhat with temperature. It is densest at four degrees Celsius, but I chose to use the density of water at room temperature -- about 20 degrees C.) Miles per hour (mi/hr) is not a convenient unit, so convert to feet per second. One mi/hr = 1.47 ft/s, so 5 mi/hr = 7.33 ft/s. Kinetic Energy, Ek, is proportional to mass and the square of the velocity. It is given by the formula Ek = (1/2)mv2. Ek = (1/2)(1.93)(7.33)2 = 51.85 ft-lb (foot-pounds) = 70.3 joules.

How do you convert 190 cubic centimeters to horsepower?
You cannot. Cubic centimetres are a measure of volume and I can have a jug containing 190 cc of water. A horsepower is a measure of energy and there is no specific energy in the 190 cc of water (other than that givem by Einstein's e = mc2) and in that case, I could replace the water by 190 cc of air - different mass so different energy. The point is, you cannot convert.
How many gallons are in a cubic foot of water?
One cubic foot of water is 7.4805 gallons.
What is the Volume of 7.48 gal of water in cubic feet?
The volume of 7.48 gallons of water in cubic feet is: one cubic foot.
What is occurring at the two temperatures on the heat curve where the graph is a flat line?
When increasing , the water is increasing in kinetic energy. When it is flat, the added energy is used to overcome the bonds between the particles. Hope This Helps.,! :-)
How many gallons of water in a cubic foot?
There are 7.48052 US gallons per cubic foot.
What kind of energy possessed water falling from a dam?
Kinetic energy. The water falling from a dam gains kinetic energy as it moves due to its velocity.
What are the energy transformations in a power plant?
The potential energy in the head of water is converted into kinetic energy in the turbine which converts the kinetic energy into electrical energy. Potential Energy of water -> Kinetic Energy -> Electrical Energy
What are the energy transformations in hydro power plants?
The potential energy in the head of water is converted into kinetic energy in the turbine which converts the kinetic energy into electrical energy. Potential Energy of water -> Kinetic Energy -> Electrical Energy
Water is potential or kinetic energy?
Water can have both potential and kinetic energy. When water is not moving but stored in a reservoir, it has potential energy. When water is in motion, such as when it flows down a waterfall or through a dam to generate electricity, it has kinetic energy.
Is flowing water kinetic or potential energy?
Flowing water is typically associated with kinetic energy, as it is in motion.
Does a water fall have kinetic energy?
Yes, it does. Kinetic energy is energy in motion. If you have a waterfall, the energy within it is constantly being moved. If it were perhaps a waterfall that was frozen over, then it would not have kinetic energy; it would have potential energy. Relative to the pool at the bottom, the water at the top has potential energy until it reaches the edge. After it spills over, each kilogram of water loses 9.8 joules of potential energy and gains 9.8 joules of kinetic energy for every meter it falls. When it reaches the bottom, all of the potential energy it had at the top has been converted to kinetic energy.
Is a water fall an example of kinetic energy?
Yes, a waterfall is an example of kinetic energy. The flowing water possesses kinetic energy as it moves downward due to gravity.
What happens to the kinetic energy of molecular motion in water when its temperature is increased?
When the water is heated, its molecules get additional kinetic energy due to it. This results in their increased velocity. As their kinetic energy gets increased, they try to overcome the force of attraction between themselves and eventually water changes into water vapour.
How is a river potential energy changed into kinetic energy?
As gravity pulls water down a slope, the water's potential energy changes to kinetic energy that can do work.
Is a fish swimming water potential or kinetic energy?
Kinetic
Does water always have the same energy?
No. The energy you might be referring to is kinetic energy which is the energy possessed by individual water molecules. An increase in kinetic energy will be percieved as and increase in temperature. Similarly a decrease in kinetic energy will be percieved as a decrease in temperature.
In what state does a fixed amount of water have the least amount of kinetic energy?
A fixed amount of water tends to have the least amount of kinetic energy in its solid state, as the molecules are tightly packed and have limited movement. This is why ice has lower kinetic energy compared to liquid water or water vapor.
