(b) A 10 pole, 125 HP, 575 V, 60 Hz, 3-ph induction motor operating at rated conditions draws a line current of 125 A and has an overall efficiency of 93%. The core loss, stator conductor loss and rotor conductor loss are 1053 W, 2527 W, and 1755 W respectively. Sketch the power flow diagram, substitute values and determine: (i) shaft speed; (ii) developed torque; (iii) shaft torque; (iv) power factor; (v) combined windage, friction, and stray power loss.
a)A thief robbing a store finds 5 items; the items are worth 8,10,7,20 and 11 dollars and weights 2,3,2,7 and 7 pounds. He wants to take as valuable a load as possible, but he can carry at most 9 pounds in his knapsack. What is the maximum worth of items that he can take? b) What if the thief somehow managed to increase the capacity of his knapsack by 2 pounds? What will be the maximum worth of items that he can take then?
(Oceanography) The pressure, P, exerted on an underwater object can be determined by this formula: P=gh is the density of water, which is 1.94slug/ft3 . g is the acceleration caused by Earth’s gravity, which is 32.2ft/sec2. h is the object’s depth in the water in feet. a. Determine the units of P by calculating the units resulting from the right side of the formula. Check that your answer corresponds to the units for pressure listed in Table 1.1. b. Determine the pressure on a submarine operating at a depth of 2500 feet.
Problem 4 Discrete Mathematics.Combinations and Permutations. (5,10,10): Soccer A local high school soccer team has 20 players. However, only 11 players play at any given time during a game. In how many ways can the coach choose 11 players To be more realistic, the 11 players playing a game normally consist of 4 midfielders, 3 defend ers, 3 attackers and 1 goalkeeper. Assume that there are 7 midfielders, 6 defenders, 5 attackers and 2 goalkeepers on the team 2. In how many ways can the coach choose a group of 4 midfielders, 3 defenders, 3 attackers and 1 goalkeeper? 3. Assume that one of the defenders can also play attacker. Now in how many ways can the coach choose a group of 4 midfielders, 3 defenders, 3 attackers and 1 goalkeeper?
3. A bacteria culture grows at a rate proportional to its size. After 2 hours, the bacteria count was 400 and after 6 hours, the bacteria count was 20,000. (a) Solve a system of equations to find k and yo for y Yoekt. (Note: it will help to assume = k is real in the symbols command). (b) Use this to determine when the bacteria count reaches 2,000,000 (exact and approximate). (c) Suppose 400 was the "initial" amount and 20,000 was the count after 4 hours. Find k and the amount of bacteria 2 hours BEFORE the "initial" time. In a print statement, explain what you notice when comparing these answers to part (a).from sympy import *from sympy.plotting import (plot,plot_parametric)import mathPlease answer in python and the stuff above as already been entered into the code.
T T e P T M SOTUPY EROUREO- B, N EXAMPLE 7.28 A lawn-sprinkling system is controlled automatically by certain combinations of the following variables. Season (S = 1, if summer; 0, otherwise) Moisture content of soil (M = 1, if high; 0, if low) Outside temperature (T = 1, if high; 0, if low) Outside humidity (H = 1, if high; 0, if low) The sprinkler is turned on under any of the following circumstances. 1. The moisture content is low in winter. 2. The temperature is high and the moisture content is low in summer. 3. The temperature is high and the humidity is high in summer. 4. The temperature is low and the moisture content is low in summer. 5. The temperature is high and the humidity is low. Use a K-map to find the simplest possible logic expression involving the variables S, M, T and H for turning on the sprinkler system.
Due to children's inmmature organ system, smaller size and larger body surface are children's fluid requirements differ greatly from adults. To calculate an infant of child's maintanance fluid requirements we use the formula below: Always convert weight from pounds to kilograms for pediatric fluids as well as medications! 100 ml/ kg for the first 10 kg of body weight 50 ml/kg for the next 10 kg of body weight 20 ml/kg for every kg over 20 kg We use this formula to calculate the hourly rate of IV fluid the child should receive in order to prevent fluid volume imbalances. 1) Calculate the daily fluid volume for a 6 kg child : 2) Calculate the daily fluid volume for a 14kg child: 3) Calculate the daily fluid volume for a 16kg child:
A farmer is planning to raise wheat and barley. Each acre of wheat yields a profit of $50, and each acre of barley yields a profit of $70. To sow the crop, two machines, a tractor and a tiller are rented. The tractor is available for 150 hours, and the tiller is available for 200 hours. Sowing an acre of wheat requires 4 hours of tractor time and 1 hour of tilling. Sowing an acre of barley requires 3 hours of tractor time and 2 hours of tilling. How many acres of each crop should be planted to maximize the farmer’s profit? (Let W be the number of acres of wheat to be planted, B the number of acres of barley to be planted and P the profit) What is the objective function for the problem?

3. Your college quadrangle is 85 meters long and 66 meters wide. When you are late for class, you can walk (well, run) at 7 miles per hour. You are at one corner of the quad, and your class is at the directly opposite corner. How much time can you save by cutting across the quad rather than walking around the edge? 5. A 1-kilogram mass has just been dropped from the roof of a building. I need to catch it after it has fallen exactly 100 meters. If I weigh 80 kilograms and start running at 7 meters per second as soon as the object is released, how far away can I stand and still catch the object?
