Hepatitis E is a potentially serious acute disease. It is caused by the hepatitis E virus (HEV). The virus targets the liver. According to the World Health Organization (WHO), 20 million cases of hepatitis E infection occur every year, and 57,000 of them result in death (WHO). It is more common in developing countries. Hepatitis E usually resolves itself but may develop into acute liver failure.
The kilowatt (kW) is equal to one thousand (10 3) watts. This unit is typically used to express the output power of engines and the power of electric motors, tools, machines, and heaters. It is also a common unit used to express the electromagnetic power output of broadcast radio and television transmitters.
Thus a 600 Watt unit â typical of older, larger refrigerators â would use 4.8 kilowatt hours daily, or 1750 per year; where a more modern 140 watt unit uses about 1.1 kWh daily, or approximately 400 per year. This is how many watts does a refrigerator use.
