Take the limit as n . Find the average value of the function over the interval [0,b]. w is work, f(x) is force as a function of distance; x equals distance. The work needed to pump the water over the pool can be obtained as W = m g h, where g = 9.8 meters per square second and h is the vertical displacement of the center of mass of the water. to 't 30 cm? So, the work done is the sum of all those works lifting the slices: integral [0,8] 4908.734 (11-y) dy = 274889 ft-lb.

how much work will it take to pump the gasoline to the top? 2.5.3 Calculate the work done by a variable force acting along a line. a. The length of the slice (parallel to the 2. Homework Equations The Find the work required to pump the water out of a spout 2 ft above the top of the tank. Draw a picture of the physical situation. It must rise (8-y)+3 = 11-y ft. (You may use the approximation g 10 m=s2 for gravity. I saw this plaque last Since the pool has height 3 m, we must lift that "layer" a distance 3- x meters which will require. 8. Submit these by clicking on the ladybug here or in a header. Work. How much work is required to pump all of the water over the side? a.

the an element of work is dW = 9810(5 y)dV = 9810(5 y)5ydy and the total work is () () 5 23 3 5 2 4 0 0 55 9810 5 5 9810 5 9810 5 1635 5 23 6 yy Wyydy == = = b. The tank is 8 feet across the top and 6 feet high.

Find the work required to pump the water out of the top of the tank. Problem 3: An upright right-circular cylindrical tank of radius 5 ft and height 10 ft is filled with water. The sides are 4 meters high. 6.5 Applications to Physics and Engineering (cont) Pumping Water Problem (cont) Spring Problem Pumping Problem: 17. (a) Calculate the initial speed of the squid if it leaves the water at an angle of 20.0, assuming negligible lift from the air and negligible air resistance. Use the Physics again gives a more precise de nition. Integrals : Time Needed to Pump Out a Tank Basic Water Distribution Math for Water Distribution Operator Certificate work done to pump all water over the edge of the trough Calculating the Power of a Pump Pressure Measurement in a Washing Machine The Maximum Amount of Work a Heat Engine can Perform 4 cx2 S 4. 3 5 2 8 0 0 ( 3 x) d x.

c) Complete- bone is separated completely by a break into 2 parts. 10 ft 6 ft 12 ft Figure 1: A tank lled with water. Example Problems Work on homework AFTER CLASS: Homework Day 17 . Start your trial now! (10 points) The following problems concern the solid of revolution generated by rotating about a given axis the region R,whichliesbetweenthex-axis and the curve y = x x2. Example \(\PageIndex{6}\): Computing work performed - pumping fluids. 8.2 Work Done Emptying a Tank The following tank problems involve pumping liquids from one height to another and determining the amount of work required to do it. 2 3 6 sx S S 3. 4. Solve for x: a) 6x 362 x Answer. Help us improve this textbook by reporting bugs, errors, and typos or telling us how it can be improved. Determine the amount of work needed to pump all of the water to the top of the tank. pi * 5^2 * dy * 62.5 = 4908.734 dy lb. : Applications of integrals. and evaluate the resulting integral to get the exact work required to pump out the desired amount of water. A water trough has a semicircular cross section with a radius of $0.25 \mathrm{m}$ and a length of $3 \mathrm{m}$ (see figure). Well use this value toward the end of our solution. 3) A conical tank is resting on its apex. We have step-by-step solutions for your textbooks written by Bartleby experts! Bundle: Calculus of a Single Variable, 9th + Mathematics CourseMate with eBook 2Semester Printed Access Card (9th Edition) Edit edition Solutions for Chapter 7.5 Problem 19E: Pumping Water A cylindrical water tank 4 meters high with a radius of 2 meters is buried so that the top of the tank is 1 meter below ground level (see figure).
