Get PriceChapter 4 uses the LRFD method for concrete design and the ASD method for masonry design. For wood design, Chapters 5, 6, and 7 use ASD. Therefore, for a single project, it may be necessary to determine loads in accordance with both design formats. This chapter provides load combinations intended for each method. The determination of individual
Get PriceFor hydraulic calculation, a Hydraulic circuit needs to be built prior to hydraulic calculation. Also, you need to gather the required data (refer to 2.1) prior to doing hydraulic calculation you need to follow the below steps: Step-1, Select the loop whose hydraulic calculation needs to do. Step-2, Mark up the hydraulic loop in PFD then in P & ID
Get PriceThe large induction motors are widely used in plants such as cement factories, steel mill, pumping stations, petrochemical plant and power plant, as ventilators, pumps, blowers etc. During the short circuit (SC), the induction motor is converted into an induction generator [1] and contributes to short-circuit current (SCC) [2]
Get PriceShort-circuit current depends on the amount of source that generates the system, the value of equipment resistance, and the overall system reactance value to the point of disturbance. Short-circuit current sources can come from generating systems, generators, synchronous motors
