Given the data below, design a section of sanitary sewer to carry these flows at minimum velocity of 2.5 fps. Assume that the minimum depth of the sewer below the street must be 8.5 ft and that an n value of 0.013 is applicable. Make a plan and profile drawing. ( Note: the invert into Manhole F must be 937 ft. Assume an invert drop of 0.2 ft across each manhole. ) Manholes (M) Distance between M (ft) Flow (gmp) Street elevations at M (ft) A-B 180 1200 A- 978 B-C 300 1450 B- 972 C-D 450 2200 C- 964 D-E 300 2500 D- 958 E-F 400 3000 E- 954 F- 949
The following wind conditions are expected: V = 10 i - 5 j mph for 0 10 hr. Draw to scale the expected streakline of the stream for t = 3, 10, and 15 hr.
Our laboratory plans to use one, 10-liter tank of refrigerant 134a every week. So off you go to check the cost of fill-ups at the two possible suppliers. At Chem Mart, the filled tank is returned to you at 10 bar and 90 C for $10.00.
A dam project specifies 97% compaction. Lab tests on the soil being used indicate that it has a maximum dry density of 1900 kg/m 3 at an optimum water content of 13.2%.
Define flow at a hydraulic jump (upstream and downstream) in terms of the types of flow and corresponding Froude number. What is the depth of water at each section (upstream and downstream) compared to critical depth
The beam is subjected to a force F=825 lb in the direction, and is supported by a pin connection at point B and a rope attached through a pin connection at point A. Problem #1: Draw a complete FBD of the beam.
Farah Manufacturing wants it's investments to double in value in 4 years, what rate of return would it have to make on the basis of (a) simple interest (b) compound interest
Member ABC is supported by cable CD and a square collar at A that fits loosely over the smooth square rod. Determine the tension in cable CD. The smooth rod is fixed at its base and cannot rotate.
Water at 20ºC flows at a velocity of 2 m/s in a 200-mm diameter horizontal ductile-iron pipe. a) Estimate the friction factor in the pipe, and state whether the pipe is hydraulically smooth or rough
A steel flat bar of dimensions 4x1x12 inches is PINNED between two copper bars of dimensions 4x2x12 inches at room temp. The PINNED assembly is then cooled by 200 degrees fahrenheit.
