How the specific gravity of fine aggregates affects the design of concrete mix? Specific Gravity Bulk specific gravity, which is measure of volume occupied in concrete including solid aggregate particles and voids between them, is required for proportioning of concrete mixture. In contrary, a lower specific gravity of sand will result in lower density of […]
What level should my radon manometer read?
What level should my radon manometer read? The readout on the manometer should be between 0.5in – 1.75in. In most cases these are acceptable levels indicating, your system is operating correct. When your Radon system is shut off the fluid should rest at zero if it does not then your manometer is low on fluid. […]
What is the height of a wave called from trough to crest?
What is the height of a wave called from trough to crest? The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength. What is the height of the wave measured from the midline to the crest of the […]

How does a DC to DC converter work?
How does a DC to DC converter work? DC-DC converters are high-frequency power conversion circuits that use high-frequency switching and inductors, transformers, and capacitors to smooth out switching noise into regulated DC voltages. Closed feedback loops maintain constant voltage output even when changing input voltages and output currents. How is chopper used in speed control […]
How big of an electric motor is needed to power a car?
How big of an electric motor is needed to power a car? There is a direct conversion between horsepower and watts: 745.7 watts is 1 horsepower. Car motors for modern vehicles range from about 50 horsepower to 500 horsepower or more. An average medium size family car might have a 150 HP motor. To duplicate […]
What connects to the lower control arm?
What connects to the lower control arm? Control arms, sometimes called “A arms,” are the core of your front suspension system. The upper control arm connects to the uppermost area of the front wheel and the lower control arm connects to the lower most area of the front wheel, with both arms then attaching to […]
What is the function of tire?
What is the function of tire? Tires are designed to support the weight of the vehicle, absorb road shocks, transmit traction, torque and braking forces to the road surface and maintain and change the direction of travel. To fulfill these four basic functions tires are made of resilient rubber and filled with compressed air. What […]
What is meant by reliability of a test?
What is meant by reliability of a test? The reliability of test scores is the extent to which they are consistent across different occasions of testing, different editions of the test, or different raters scoring the test taker’s responses. How do you define reliability requirements? There are four basic ways in which a reliability requirement […]
