What is compressible and incompressible flow? Incompressible flow means flow with variation of density due to pressure changes is negligible or infinitesimal. All the liquids at constant temperature are incompressible. Compressible flow means a flow that undergoes a notable variation in density with trending pressure. What is the difference between compressible and incompressible fluids? The […]

How do you calculate the frequency of an oscillator ring? 1 ftest = _____________ n × 2T × 2m Page 4 4 where ftest is test frequency, T is the average gate-delay time, n and m are the number of stages in the ring oscillator and the number of frequency dividers respectively. For example, if […]

What is fairness in economics? A large part of fairness research in economics has focused on prices and wages. With respect to prices, for example, consumers are generally less accepting of price increases as result of a short term growth in demand than rise in costs (Kahneman et al., 1986). What do behavioral economists believe? […]

What happens to diffraction pattern when distance between slits within the grating is increased? If we move the screen farther from the double slit, the screen will intercept the light from the grating after the bright lines in the pattern have been able to spread out farther, increasing the distance between the bright spots on […]

What is the process of dehumidification? The dehumidification process is the inverse of adding water to the room with an evaporative cooler, and instead releases heat. Therefore, an in-room dehumidifier will always warm the room and reduce the relative humidity indirectly, as well as reducing the humidity more directly, by condensing and removing water. What […]

How do you calculate VC in a RC circuit? RC Charging Circuit Example No1 At 0.7 time constants ( 0.7T ) Vc = 0.5Vs. Therefore, Vc = 0.5 x 5V = 2.5V. At 1 time constant ( 1T ) Vc = 0.63Vs. Therefore, Vc = 0.63 x 5V = 3.15V. 1 time constant ( 1T […]

How do you calculate cost of excavation? Then the cost of 10m3 of excavation can be calculated as: No. of days required for 10m3 excavation = = 0.04125 days. How much does it cost to excavate for a house? In this regard, the Perrier guide gives us an estimate of the price: “It can cost […]

What is system call explain any five system calls which are used in Linux? Open() A program initializes access to a file in a file system using the open system call. Read() A program that needs to access data from a file stored in a file system uses the read system call. Write() What is […]

What is service entrance cable? The definition of service-entrance cable in 338.2 is “a single conductor or a multiconductor assembly provided with or without an overall covering, primarily used for services.” Type USE cable, containing two or more conductors, is permitted to have one conductor that is uninsulated. What are service entrance conductors protected against? […]
