1.Two tangent intersect at angle of 30 degree ad 40 minute at sta 90+10 and are joined by a 4 degee 30 minute curve. using the tabla for radii and dflection distance what is the tangent distance if the degree of curve is base on a 100-ft chord ? wich one is the right awnser is A 349.00ft or B349.11 or C 349.20 or D 349.50 wich one is correct
2.A motorcycle starts from rest at time t=0. The force on it from t=0to 30 seconds is F=300-9t. The combined mass of the motorcycle andthe rider is 225 kg. Use the Impulse and Momentum method to findthe magnitude of the velocity at t=30 seconds.
a whirlpool is modeled as the combination of a free and a forced vortex. the maximum velocity in the whirlpool is 10 m/s, and the radius at the juncture of the free and the forced vortex is 10m.
calculate the: 1) molar concentration of metal ion in the stock coagulant solution; 2) coagulant feed rate (into the process water flow stream) in units of L/day and L/min; 3) alkalinity consumed (in the process water flow stream) in units of mg/L..
The siphon crown is 1.2m above the water surface elevation of the reservoir and a length 10m away from the siphon entrance. If the siphon diameter is 30 cm, if the friction factor is .02, and the headless coefficient are .2 (inlet) and 1 (exit),
Oil flows through the Trans-Alaska pipeline. Because oil is viscous, you might think that the flow is laminar. (a) What is the minimum flowrate (m3/s) for which the flow would likely be laminar.

The Permeability of a semi-impervious soil was evaluated in a falling-head permeameter whose head decreased from 40 to 15 inches in 5min. The body diameter was 0.1 inch, and the sample length and diameter was 2 inches.
Determine the acceleration when t = 4 s, the displacement from t = 0 to t = 10 s, and the distance the particle travels during this time period.
(a) Compare the crystalline state in metals and polymers. (b) Compare the noncrystalline state as it applies to polymers and ceramic glasses
Calcium sulfate (CaSO4, solubility product Ksp=2*10^-5 M^2), is added to initially pure water, such that solid CaSO4 remains at equilibrium. (Assume the sulfate does not participate in reaction other than the solubility product; no HSO4- formed).
Soil with a unit weight of 19.65 kN/m^3 is loaded on the ground surface by a strip load of 1.5 m wide. The strip load is 365 kN/m of wall length. Determine the vertical stress increment due to the strip load and the total pressure
A 250 cubic meter reaction tank contains a waste water having an ultimate BOD concentration of 755 mg/L. If the BOD reaction rate constant is -0.352/day, how much BOD is remaining after 12.0 days
