In the simplified depiction of an ice rink with an ice resurfacing machine operating shown in Figure 4-22, points 1 and 3 represent the ventilation air intake and exhaust for the entire ice rink, and point 2 is the resurfacing machine exhaust. Conditions at each point are (C indicates the concen-tration of carbon monoxide, CO):
In 1952 E. S Crump developed the triangular weir shape shown in Fig, the front slope is 1:2 to avoid sediment deposition, and the rear slope is 1:5 to maintain a stable tail water flow. The beauty of the design is that it has a unique discharge co..
water flows at a velocity of 25 ft/s at a depth in a rectangular channel 16 feet wide. Determine the downstream depth necessary to form a hydraulic jump, the head loss through the jump and the horsepower dissipated in the jump.
Design a 300 + sl m long variable graded terrace for a land having an average slope of 2 %. Maximum permissible velocity of water in the terrace channel is 60 cm/sec. The most sever rainfall expected in 10 yr RI has an intensity of 9 cm/hr.
Neglecting the mass of the pulley and the effect of friction in the pulley and between block A and the horizontal surface. Determine (a) the initial tension in the table (b) the initial acceleration of Block A (c) the initial acceleration of Block..
Find the speed of sound for air at 100 kPa at the two temperatures 0?C and 30?C. Repeat the answer for carbon dioxide and argon gases.
How do you determine the correct number of significant figures to use for each distance measurement? Be specific.(pacing,EDm, GPS and tape), Which measurement method would you choose to determine the square footage of your house? Why would you choos..
A flow of 0.1 cum/s flows down in a rectangular channel of width of 0.6m and having and adjustable bottom slope. If chezys constant C is 56, determine the bottom slope necessary for uniform flow with a depth of flow 0.3m. Also find the conveyance of ..
A rectangular channel 5 m wide carries a discharge of 10 m^3/s at a uniform depth of 3 m. The channel is running on a slope of 0.0025 m/m. Estimate wall shear stress and friction velocity. Assume the density of flowing water as 1000 kg/m^3.
What is the governing equation for two-dimensional flow, and what are the methods adopted for its solution for practical problems?
Calculate the maximum bending stress due to the load q if the beam has a rectangular cross section with width b=140mm and height h=240 mm.
Suppose a family of four, living in a home with an area of 100x50ft connects its stormwater drain to the sewer. Assume that 1in of rain falls over 1 day
calculate the change in entropy of a gas of mass 8kg when 100 kj of heat energy is supplied to the gas. the temperature of the gas remains constant at 100 c during the heat transfer process
