One liter of a solution is made by adding 3grams of acetic acid (HAc) to distilled water. The molecular weightof acetic acid is 60.052. The acid dissociation constant for aceticacid is KA= 1.75 x 10-5. The chemical equation for thedissociation of acetic acid into hydrogen ions and acetate ions isH+ + Ac-. Find the percentage of aceticacid ionized in the solution.
a lower tank contains water while an upper tank contains air with a negligible concentration of water vapor. a tube
A 100% saturated soil has a wet unit weight of 112.8 lb/ft^3, and its water content is 42%. Find the void ratio and specific gravity of solids.
The block is released from rest when the spring is unstretched (at x=0). We wish to show that the ensuing motion of the block is simple harmonic. Call the initial configuration of the system that existing just as the block is released from rest.
The inlet gas velocity is 16m/s and the particle density is 1.6 gm/cc. The working temperature of the process is 400K. Estimate the particle size that will be collected with 50 percent collection efficiency.
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 PVC pipe with a diameter of 30 inches will carry a flow of 20 cfs. the bottom slope is 0.005 and the roughness coefficient is 0.015. determine the normal depth, critical depth, velocity and the froude number.
The peak-hour volumes at two locations were counted and found to be equal. However, the PHFs were .85 at the first location and .60 at the second. Describe the difference between the two locations if t=5 min.
In a venturi meter the gage pressure is 120 kPa whencavitation just starts to occur. If the Diameter is 40 cm and theneck diameter is 14 cm, what is the water discharge in the system for this condition of incipient cavitation
Determine the major and minor principal stresses at failure and the effective stress friction angle (assume c' = 0). Plot the Mohr diagram.
According to the design philosophy in the AASHTO Specifications, how does a heavy truck parked on a prestressed bridge girder effect the nominal shear resistance of the girder
Compacted one cylinder of the soil describes above problem 1 to compare the new results with shown above. The data obtained included a water content of 32.5% and a total density of 121.9 pcf. Comment on these new findings.
If OA has a constant counterclockwise angular velocity of 10rad/s, calculate the angular acceleration of link AB and link BC for the position where the cordinates of A are x=-60mm and y = 80mm.
