A natural-draft cooling tower is to remove 50 MW of waste heat from the cooling water that enters the tower at 42°C and leaves at 27°C. Atmospheric air enters the tower at 1 atm with dry- and wet-bulb temperatures of 23 and 18°C, respectively, and leaves saturated at 37°C. Determine (a) the mass flow rate of the cooling water, (b) the volume flow rate of air into the cooling tower, and (c) the mass flow rate of the required makeup water.
A 2ft diameter hemispherical plexiglass "bubble is to be used as a special window on the side of an above-ground swimming pool.
A slender 9 lb rod can rotate in a vertical plane about a pivot at b. a spring of constant k=30 lb/ft and of unstretched length is 6in is attached to the rod as shown.
A spherical pressurevessel of 1.2m outside diameter is to be fabricated from a steelhaving an ultimate stress of σU450 MPa. Knowing that a factor of safetyof 4.0 is desired and that the gage pressure may reach 3 MPa,
A constant-head permeability test was conducted on a sample of fine silica sand. The cross-sectional area of the sample was 60 cm2 and its length was 150 mm.
The winch consists of a drum radius 4 in., which is pin connected at its center C. At its outer rim is a ratchet gear having a mean radius of 6 in. The pawl AB serves as a two-force member (short link) and keeps the drum from rotating.
the unit weight of normal weight reinforced concrete is commonly assumed to be 150 lb/ft cubed. find the weight per lineal foot (lb/ft) for a normal weight reinforced concrete beam that: a. has a rectangular cross section 16 in.
Calculate the temperature increase which would induce maximum compression in the wall of the vessel equal to the maximum tension. young's modulus for steel can be taken as 200Gpa and the coefficient of thermal expansion as 12*10^-6mm(mm Celsius).
What are the bearings of the sides CD,DE,EA, and AB if the side CB has a bearing S 20° 44' 36" W, point A is westerly of B and interior angles in each apex are as follows: A = 95° 14' 23"; E=81° 16' 54"
A soil sample with a water content of 14.5% and unit weight of 128.2 lb/cu. ft. was dried to a unit weight of 118.8 lb/cu. ft. without changing its void ratio. What is its new water content (in %)?
A paper mill releases 1 m^3/s of treated effluent at 75 C, which is mixed with captured rain water at 13 C before it is released to a nearby river. Regulations dictate that the effluent discharge cannot be over 20 C.
As part of a drainage improvement project, a drainage ditch will be straightened and cleaned. As a result, the lenght of the ditch will decrease from 1800 ft to 1400 ft and the mannings roughness factor will be reduced to 0.018 from 0.022.
Suppose that F1 ο G2 =F1ο G1 then F : S→ T, G1 : T → U, G2 :T →U,. Define a function F : R2 ? R2 by F(x, y) = (x +y, x - y). . Show that if F is onto, Suppose that G1ο F = G2 ο F.
