What are double pipe heat exchangers used for? Double-pipe heat exchangers are used in many industries because of their low design and maintenance costs, flexibility, and low installation costs [25]. They are mainly used for sensible heating or cooling of process fluids in applications of small heat transfer areas of up to 50 m2 [38]. […]
What is an advantage of a closed loop system over an open loop system?
What is an advantage of a closed loop system over an open loop system? Closed-loop control systems have many advantages over open-loop systems. One advantage is the fact that the use of feedback makes the system response relatively insensitive to external disturbances and internal variations in system parameters such as temperature. What are the advantages […]
How close can you work to overhead power lines?
How close can you work to overhead power lines? You should manage the risks if you intend to work within a distance of 10 m, measured at ground level horizontally from below the nearest wire. 12 The most effective way to prevent contact with overhead lines is by not carrying out work where there is […]
Does the Internet affect the political process?
Does the Internet affect the political process? The Internet may also change the way in which political groups and politicians conduct election campaigns, keep in touch with constituents, and forge alliances with other groups or individuals. The Internet may also enable small groups with limited resources to participate in the political process. How does the […]
What is pitch in pinion gear?
What is pitch in pinion gear? The pitch of a gear is defined as the distance between two identical points on two adjacent gear teeth. If you draw a circle that is one inch in diameter and equally space 16 teeth around this circle wherein the pitch diameter is overlaying the one-inch circle, then you […]

What are some ways that the strength of an electric field between two parallel plates can be increased?
What are some ways that the strength of an electric field between two parallel plates can be increased? Increasing the charges of the plates, by increasing the battery strength it will increase the plate charges. In addition, decreasing the distance between two plates, increases the strength of an electric field between two plates. Where is […]
What is the isentropic efficiency of a turbine?
What is the isentropic efficiency of a turbine? Hence, the definition of isentropic efficiency of turbine is the ratio of the actual work output of the turbine to the work output of the turbine if the turbine undergoes an isentropic process between the same inlet and exit pressures. Compressors and pumps, when undergo a steady-flow […]
How triangular wave is generated?
How triangular wave is generated? ➢ Triangular waveform can also be generated by integrating square wave from an astable multivibrator. ➢ The cycle from the square wave to the next operational amplifier repeats and generates a triangular waveform. ➢ Triangular waveform can also be generated by integrating square wave from an astable multivibrator. What is […]
What happens when you spin a bearing?
What happens when you spin a bearing? A spun bearing is bad news because it usually seizes itself around the crankshaft journal. Spun rod bearings are the most common failure. A spun rod bearing will tear up the big end bore in the rod, ruin the rod journal on the crankshaft, and sometimes break the […]
