How can the efficiency of a heat exchanger be increased? Conventional shell and tube heat exchangers use simple segmental baffles. It can be replaced by helical baffles, which increase the heat transfer efficiency and reduce pressure losses. Their usage is demonstrated in the primary circuit of IV. Does heat transfer increase with flow rate? In other words, the rate of heat transfer is directly proportional to mass flow rate. If

How do load commutated inverters work? Load Commutated Inverter (LCI) is a system with an input thyristor bridge and an output thyristor bridge. The output bridge operates at low speed by turning on a set of 2 thyristors to pass the DC current into the generator’s stator to cause it to rotate. What does line-commutated mean? The term line-commutated indicates that the conversion process relies on the line voltage of

Why the common collector amplifier is also called as an emitter follower? Common Collector/ Emitter Follower Transistor Amplifier Basics. In the Common Collector transistor configuration, we use the collector terminal as common for both input and output signals. This configuration is also known as emitter follower configuration because the emitter voltage follows the base voltage. Why common collector can be used as a voltage buffer? Although the common collector amplifier

Why are Teflon coated bullets called cop killers? Various gun control organizations in the U.S. labeled Teflon-coated bullets with the epithet “cop killers” because of the supposedly increased penetration the bullets offered against ballistic vests, a staple of the American police uniform. What caliber are cop killer bullets? 22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25 percent of

Can WannaCry infect Linux? Wannacry is an mask that exploits security vulnerabilities in Windows therefore it cannot infect Linux machines. Does wine make Linux more vulnerable? Linux is considered to be less prone to malware compared to other operating systems, and as a result Linux users rarely run anti-malware. Wine is a popular compatibility layer for running Windows programs on Linux. The level of security risk that Wine poses to

Where do Mon Calamari come from? The Mon Calamari people are a humanoid, aquatic species with high-domed heads, webbed hands and large, goggle-like eyes. They hail from the oceans of Mon Cala, a planet they share with the Quarren. During the Clone Wars, differences between the two cultures were fanned by Separatist troublemakers to erupt in civil war. Does Mon Calamari have land? They were a fish-like amphibious humanoid species

Will a 120 volt LED work on 12 volts? Yes you can. But it will not glow that bright because the bulb is rated 120 volts to get the desired brightness. If you’ve ever tried it, you would find that even at 50\% rated voltage, the bulb will be useless. How do you hook up LED strip lights to a 12 volt battery? First, press the power button on the
