5. Consider a three-component standby system in which two units are normally on-line. Both on-lin...
A standby mechanical system is composed of three independent and identical motors (i.e., one unit operating and the other two on standby). The motor constant failure rate is 0.0009 failures/hour. Calculate the system reliability for a 200-hour mission for this mechanical system.
Consider a system consisting of three exponential units, connected in series, with the following failure rates (in failures per hours): λ1 = .0002 λ2 = .0005 λ3 = .0001 What is the reliability equation for the system? What is the reliability of the system after 150 hours of operation What is the MTBF for the system
Consider the single-line diagram of the three-phase power system shown in Figure 1. Component ratings are as follows: Generator G1: 750 MVA, 18 kV, X0.2 per unit Generator G2: 750 MVA, 18 kV, X 0.2 per unit Synchronous Motor M: 1,500 MVA, 20 kV, X-20% A-Y Transformers Ti, T2, T's, & T.: 750 MVA, 500 kV Y/20 kV A, X = 10% Y-Y Transformer T's 1,500 MVA, 500 kV Y/20 kV Y, X-10% ne L:X (a) Using bases of 100...
Consider a simple two-stage assembly line that has two identical robot arms (one for each stage). The system is functioning if a part can receive processing (i.e. the robot arm is working) in both stages of an assembly line. Your supervisor knows that a pure series system is not the most reliable and has authorized the purchase of two additional arms to be used to add redundancy to the system. However, she is unsure of the best way to set...
Consider the system shown in the single-line diagram of Figure (3). All reactances are shown in per unit to the same base. Assume that the voltage at both sources is \(1 \mathrm{p}\).u. a- Find the fault current due to a bolted- three-phase short circuit at bus \(3 .[10\) points \(]\) b- Find the fault current supplied by each generator and the voltage at each of the buses 1 and 2 under fault conditions. \([10\) points \(]\)
please help me with answering all questions 4-10 thank you ? Two/three or more component system: practice the algebra! INCLUDE ALL UNITS! 3. A sample of a metal with a mass of 212g is heated to 125.0°C and then dropped into 375g of water at 24.0°C. If the final temperature of the water is 34.2°C, what is the specific heat of the metal? (Hint: treat as 2-component system) 1pt work space: 4 water at 18.3°C. If the temperature of the...
Consider the system of two equal masses M joined together by three identical springs of spring constant k. *2 x1 As shown in the figure, assume the left mass has been displaced a from its equilibrium position, and the right mass has been displaced distance a distance T2 from its equilibrium position. In terms of ri and z2 i. How much has the left spring been stretched/compressed from equilibrium? ii. How much has the middle spring been stretched/compressed from equilib-...
solve no: 3.14 , 3.16, 3.19 please show each step and solve for beginners 120 Power System Analysis 3.12. A single-phase system similar to that shown in Figure 3.11 has two transformers A-B a B-C connected by a line B feeding a load at the receiving end C.

Game Description: Most of you have played a very interesting game “Snake” on your old Nokia phones (Black & White). Now it is your time to create it with more interesting colors and features. When the game is started a snake is controlled by up, down, left and right keys to eat food which appears on random locations. By eating food snake’s length increases one unit and player’s score increases by 5 points. Food disappears after 15 seconds and appears...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
