 Water leaking from a trough 2016-12-28 From Kathryn:A trough is 6 m long, and has uniform cross-section of an equilateral triangle with sides 1 m. Water leaks from the bottom of the trough, at a constant rate of 0.1 m3/min. Find the rate at which the water level is falling when the water is 0.2m deep.Answered by Penny Nom. A trough with a triangular cross section 2016-05-21 From Clarice:A trough having an equilateral triangle end sections has sides equal to 0.4 m and 7m long.what is the volume of the liquid in the container if the depth of the water is one half the depth of the trough?Answered by Penny Nom. A trough of water 2011-05-01 From alvin:A trough is formed by nailing together, edge to edge, two boards 11 ft. in length, so that the right section is a right triangle. If a 15 gallon of water are poured into the trough and if the trough is held level so that a right section of water is an isosceles right triangle, how deep is the water? (231cu.in=1 gal.)Answered by Penny Nom. A water trough 2010-10-22 From Jasmine:A water trough is 8 m long and its cross-section is an isosceles trapezoid which is 90 cm wide at the bottom and 120 cm wide at the top, and the height is 30 cm. The trough is not full. Give an expression for V , the volume of water in the trough in cm^3, when the depth of the water is d cm.Answered by Stephen La Rocque. A trough of water 2009-09-15 From Darrell:A trough that measures 4 feet long, 22 inches wide, and 18 inches high will be mounted on a support stand. If the trough weighs 50 pounds when empty, approximately how many pounds must the stand be able to hold when the trough is full of water?Answered by Penny Nom. The volume of fluid in a semi circular trough 2008-10-10 From Kerry:How do I find the volume of fluid in a semi circular trough?Answered by Penny Nom. Related Rates (a water trough) 2007-11-07 From Christina:A rectangular trough is 3ft long , 2ft across the top and 4 ft deep. If water flows in at the rate of 2ft^3/min, how fast is the surface rising when the water is 1 ft deep ?Answered by Stephen La Rocque. Related rates 2007-10-26 From David:A trough is 12 feet long and 3 feet across the top.(look like an upsidedown triangle square). Its ends are isosceles triangles with altitudes of 3 feet. a) If water is being pumped into the trough at 2 cubic feet per minute, how fast is the water level rising when h is 1 foot deep? b) If the water is rising at a rate of 3/8 inch per minute when h=2, determine the rate at which water is being pumped into the trough. thank you so much for helping me outAnswered by Stephen La Rocque. A triangular trough 2007-07-19 From janine:A trough is formed by nailing together, edge to edge, two boards 11 ft. in length, so that the right section is a right triangle. If a 15 gallon of water are poured into the trough and if the trough is held level so that a right section of water is an isosceles right triangle, how deep is the water? (231cu.in=1 gal.)Answered by Penny Nom. Volume in a triangular water trough 2007-06-24 From David:A water trough has sloping sides of length 500mm making it triangular in cross section, with vertical ends. The width at the top is 600mm and the length is 2.0 metres. (i) Calculate the capacity of the trough, giving your answer accurate to the nearest litre. (ii) Find out the depth of the water when the trough is half full.Answered by Stephen La Rocque. Water in a triangular trough 2007-01-30 From Trina:the trough is 5 feet long and its vertical cross sections are inverted isosceles triangles with base 2 feet and height 3 feet. water is draining out of the trough at a rate of 2 cubic feet per minute. at any time t, let h be the depth and v be the volume of water in the trough. a. find the volume of water in the trough when it is full b. what is the rate of change in h at the instant when the trough is .25 full by volume? c. what is the rate of change in the area of the surface of the water at the instant when the trough is .25 full by volume?Answered by Penny Nom. How fast is the water level rising when the water is 1 meter deep? 2006-10-19 From Don:The cross section of a 5-meter trough is an isosceles trapezoid with a 2-meter lower base, a 3-meter upper base and an altitude of 2 meters. Water is running into the trough at a rate of 1 cubic meter per minute. How fast is the water level rising when the water is 1 meter deep?Answered by Stephen La Rocque. Volume of a trough 2000-12-09 From Matt:I have been given the information of the length of the trough, and the end pieces are isosceles triangles, and two equal sides of the triangle are given. I cannot seem to find the answer, nor anything in my book relating to the question. Answered by Harley Weston.
