PkW = 0.85 (230 V) (10 amps) / 1000 = 1.96 kW. Php = 0.85 (230 V) (10 amps) / 746 = 2.62 hp. Electrical power is in general rated in watt (W) or horsepower (HP). A horsepower is a unit of power equal to 746 watts or 33,000 lb.ft per minute (or 550 lb.ft per second). A watt is equal to the power produced by a current of 1 amp across the potential difference of 1 volt. A watt is 1/746 of 1 horsepower. Even if the watt is the base unit of electrical power, it is common to rate motor power in either horsepower or kilowatts.
Also, ultrasound is used for real-time imaging of the location of the tip of a catheter as it is inserted in a blood vessel and guided along the length of the vessel. It can also be used for minimally invasive surgery to guide the surgeon with real-time images of the inside of the body.
