What is the most energy efficient light bulb? Incandescent bulbs and halogen bulbs have the highest wattage, making them less energy-efficient choices. CFL bulbs use fewer watts, but LED bulbs are the real winner in energy efficiency—an 8 or 9-watt LED bulb emits as much light as a 60-watt incandescent bulb. What is the efficiency […]
How do you find the overall heat transfer coefficient?
How do you find the overall heat transfer coefficient? Composition = the overall heat transfer coefficient (W/(m2•K)) = the contact area for each fluid side (m2) (with and expressing either surface) = the thermal conductivity of the material (W/(m·K)) = the individual convection heat transfer coefficient for each fluid (W/(m2•K)) = the wall thickness (m). […]
How is data input into a computer?
How is data input into a computer? Input: Getting Data from the User to the Computer. Some input data can go directly to the computer for processing. Input in this category includes bar codes, speech that enters the computer through a microphone, and data entered by means of a device that converts motions to on-screen […]
How many volts does a single solar cell produce?
How do you find the closed loop transfer function from an open loop transfer function?
How do you find the closed loop transfer function from an open loop transfer function? Closed-loop System Transfer Function To find the transfer function of the closed-loop system above, we must first calculate the output signal θo in terms of the input signal θi. Note that the error signal, θe is also the input to […]
What regulates NRC?
What regulates NRC? The NRC regulates commercial nuclear power plants and other uses of nuclear materials, such as in nuclear medicine, through licensing, inspection and enforcement of its requirements. Which government agency regulates nuclear power plants? The Nuclear Regulatory Commission (NRC) What federal regulation governs the use of radioactive materials? How much is a gram […]
How were the spectacular rock formations of Arches National Park formed?
How were the spectacular rock formations of Arches National Park formed? Arches National Park is located in a region above a large layer of salt. This salt layer is the result of the evaporation of a sea that existed over 300 million years ago. This change of state caused the salt layer to push the […]
How does a 2 way hydraulic cylinder work?
How does a 2 way hydraulic cylinder work? Double acting Cylinders, Hydraulic Cylinders, Hydraulic Cylinders Repairs, Hydraulic Cylinder Manufacturers, A double acting cylinder alternates cycles of pressurized fluid to both sides of the piston and creates extend and retract forces to move the piston rod, permitting more control over the movement. What is the rod […]
What is the role of the regulator?
What is the role of the regulator? Monitoring compliance with contractual obligations to the government and users, and other legal and regulatory requirements. Imposing penalties for non-compliance. Administering tariff adjustments and periodic reviews. Establishing accounting standards and undertaking operator’s cost and performance analysis. What is the function of the regulator in a power supply? Voltage […]
What are the 3 types of compressors?
What are the 3 types of compressors? The three most common air compressors are the reciprocating, rotary screw and centrifugal. Reciprocating air compressors are considered positive displacement machines, which means they increase the pressure of the air by reducing its volume. What are the types of compressor? The four most common types of air compressors […]
