A bulbous bow is a design feature that reduces drag on boats, improving fuel efficiency and reducing wave size. It was developed independently in various countries, including the US and Japan, and is most effective on larger vessels. The bulb is mounted below the waterline and is not visible while the ship is running. A […]
UV light bulbs produce short wavelength electromagnetic radiation that is invisible to the naked eye. They are used in medical and cosmetic treatments, pest control, safety testing, and curing adhesives. The bulbs consist of a glass envelope with inert gases and mercury, and a phosphor coating that shields the radiation. UV light is used for […]
UV light bulbs produce ultraviolet light, which is invisible to the naked eye and occurs naturally in sunlight or artificially in electric arcs and lamps. Different types of UV bulbs emit specific wavelengths of UV radiation and are used for medical treatments, pest control, safety testing, and curing adhesives. The bulbs contain a pressurized mixture […]
Squeeze bulbs are versatile devices used to pump fluids and gases, with medical applications such as blood pressure cuffs and ventilators. They can also be used for controlled suction and to transfer fluids, and are typically made of rubber. A squeeze bulb is a device that can be used to suck up or pump fluids […]
A bulb baster is a kitchen tool used for basting and removing liquids from pans. It consists of a cylinder and a bulb made of plastic, silicone, or rubber. Basting keeps food moist and flavorful, and the tool can also be used for applying marinades and removing excess liquid. Optional tips include a basting brush, […]
Thomas Edison improved upon previous inventions to create the first commercially efficient and widely used light bulb. Many inventors worked on inventing a long-lasting incandescent light bulb, but Edison succeeded in 1879. Nikola Tesla’s AC technology paved the way for more powerful electricity and light. The incandescent light bulb is inefficient, and many countries have […]
Wet bulb temperature is the lowest air temperature due to evaporative cooling, measured with a psychrometer or glass bulb thermometer. It is estimated using dew point and dry bulb temperature and is used to determine the efficiency of evaporative coolers in dry regions. Wet bulb temperature is the lowest measure of air temperature that results […]
A “nuclear light bulb” is a type of nuclear-powered rocket engine or power source. It uses a quartz wall to separate the coolant/propellant from the nuclear fuel. It could be used for rocket propulsion or to generate electricity through photovoltaics. It offers superior propulsion and complete reusability, with a payload equal to 30% of its […]
Germicidal bulbs emit low-wattage UV light to disinfect medical equipment, food, and water. They come in low and medium pressure bulbs, with the latter being used for water purification. However, they pose health risks to humans, including skin cancer and eye damage. Precautions must be taken when handling them. In an effort to fight bacteria […]
Dry bulb temperature measures air temperature without considering moisture content. It is important for industries that dry materials using heated or unheated air. Evaporative coolers require high dry bulb and low dew point temperatures. A thermometer should be placed away from heat sources to measure dry bulb temperature. Psychrometric graphs can determine relative humidity and […]
