Engineering 151 Final Exam Module 10 through 14
A simple plate capacitor can store 6.5x10-5 C at a potential of 10,000 V. What dielectric constant must the material between the plates have if their area is 6.0x10-5 m2 and they are 0.16 mm apart?
It is desired to produce 5 cubic yards of concrete with a ratio of 1:1.8:3.5 (by weight) of cement, sand, and gravel. What are the required amounts of the components if 5.5 gallons of water per sack of cement is to be used? Assume the free moisture contents of the sand and gravel are 3% and 0.75% respectively. The specific gravities of the cement, sand, and gravel are 3.15, 2.65, and 2.65 respectively. (1 sack of cement weighs 94lb, and 1ft3 of water=7.48 gallons). Give the answere for cement in sacks, the sand and gravel in pounds, and the water in gallons.
