A confined aquifer has a specific storage of 1.8 x 10-5 /m. The porosity is 0.31, and the water compressibility is 4.5x10-10 /Pa. (A) What is the compressibility of the aquifer skeleton [5 pts]?b) For the aquifer skeleton compressibility you just calculated, what would the aquifer specific storage be if porosity were 50%.

c)What effect does the increasing porosity have on aquifer storativity? Why?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Fluids at rest possess no flow energy. a)- true b)- false

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
