The composition of moist air is given on a molar basis to be 78 percent N2, 20 percent O2, and 2 percent water vapor.
Determine the mass fractions of the constituents of air
The disk has an initial clockwise rotation speed of 8 rad/sec and at t=0 begins a counter-clockwise acceleration of ? = 0.6 t1.88. What is the speed of point A at t=3 sec? Point A has a radius of 2 ft.
A train moving at 100 km/hr decreases its speed to 80 km/hr in 3.5 seconds. How far, in meters, did the train travel during this time
A vertical semicircular disc of 2 m diameter is submerged in a liquid of SG = 0.76 such that its diameter, which is at the top, is parallel to the liquid surface at a depth of 3 m. What is the pressure force on one side of the disc?
Determine the IRR of building the corrosion-resistant tower. (Hint: Calculate interest rates from 7% to 11% using formulae provided in tables).
given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t Cedar points millennium force accelerates from 10 mph to 93 mph in 4.5 seconds. assuming acceleration is constant, find acceleration in ft/sec^2 and distance traveled in meters
A pump delivers 60 degrees F water at 2000 gpm through a vertical pipeline 300 ft high. Find the minimum horsepower input to the pump. Assume that atmospheric pressure exists at both the pump inlet and the pipeline outlet.
Assuming that the nozzle is well insulated and operating at steady state and that the air behaves as an ideal gas, calculate (a) the mass flow rate of air in kg/s, (b) the exit area of the nozzle in m^2,
A spherical drop of water has r = .1mm . If the surface tension of water is 72 dynes/cm, calculate the pressure difference across the interface.
A reservoir cover is 12,000 acres and is 20 feet thick. The formation has initial porosity of 0.25. The pore volume compressibility of the reservoir rock is 3.0 x 10^(-6) psi^(-1) .
explain how you would determine the mole fraction of the gas dissolved in the liquid at the interface at a specified temperature
if D has a mass of 600 kg, determine the required mass of C, the maximum sag h of the cable, and the length of the cable between the pulleys A and B. The Beam has a mass per unit length of 50 kg/m.
A smooth hump is placed in the bottom of the channel. What would be the depth of flow over a 3 ft high jump. How high can the hump be made without backing flow up What would be the depth of flow over and just upstream of a 6 ft high jump
