1.Calculate the required area of an air to air heat exchange to cool 20,000 cfm from 1200 F to 400 F. Assume ambient air at 80 F will be heated to 800 F by the exchange. Assume heat losses are 10 % and that the overall heat transfer coefficient is 1.0 Btu/hr-ft^2- °F
Two immiscible fluids are in contact. Fluid I is denser and is also well mixed. The concentration of species a is cao everywhere within this fluid and the temperature in fluid I is held constant at To.
Calculate the percipitable water (mm) in a 10-km high standard atmoshperic column if the surface conditions are temperature=20 degrees C, pressure=101.3 kPa and the laspe rate is 6.5 degrees C/km.
The two outer bars (material A) are identical. The cross- sectional area of the middle bar (material B) is 31.544% larger than the cross- sectional area of one of the outer bars. Also, the modulus of elasticity of material A is twice that of mater..
The uniform 30 kg bar OB is secured to the accelerating frame in the 30 degree position from the horizontal by the hinge at O and roller at A. if the horizontal acceleration of the frame is a equals 20 m/s^2
Use the strain-transformation equations to determine (a) the in-plane principle strains and (b) the maximum in-plane shear strain and average normal strain.

A company near City X want's to know how much benzene they can release into River Y. City Z is 85.5 miles downstream from City X. City Z doesn't want to have Benzene levels higher than 0.0000015 g/L.
If all trucks travel at a speed v', cars at a speed v, and the fraction of vehicles passing a stationary observer that are trucks is p, what fraction of vehicles would be trucks on a photograph
three different materials designated a b and c are tested in tension using test specimens having diameters of 0.755 in.
The coordinates for Point A, Point B and Point C are 5859.28N, 9331.56E and 8501.95N, 7911.60E and 10,500.00N, 8000.00E respectively. An angle right of 220°31'00" is turned when the backsight is B
The truck is driving onto the stationary barge at the speed of v1. The masses of the truck and the barge are m and M, respectively. The barge is free to move on the water and the water resistance is to be ignored.
