A sound wave is observed to travel through a liquid with a speed of 1500 m/s. The specific gravity of the liquid is 1.5. Determine the bulk modulus of elasticity, Ev, for this fluid.
It rains 3.0 in. on a 20.0 acre watershed. What is the volume of rainfall excess if 30% of the watershed area is a lake and infiltration on the soil is estimated at 1.0 in. What is the total volume of runoff
a moist soil has a total unit weight of 110 pcf and a water content of 6 percent. assuming that hte dry unit weight is to remain constant , determine how much water , in gallons per cubic yard, must be added to increase the water content to 12 per..
if the enginer is mounted floatiing on very weak spring, what is the amplitude of the vertical vibration of the engine? (b) if the engine is mounted solidly on a rigid foundation, what is the alternating force amplitude transmitted? Assume the con..
Assuming Stokes behavior, calculate the terminal settling velocity in standard air for the following particles: (a). diameter = 10 micrometers, specific gravity =1.2; and (b) diameter = 4 micrometers, specific gravity = 2.0.
Using Raoult's Law or Henry's Law, as appropriate, calculate the pressure and mole fractions in the vapor phase for a system containing a liquid that is 0.3% N2 and 99.7% water (by moles) in equilibrium with its vapor at 80 °C.
A block begins to slide down a ramp after being elevated to an angle of 47.5 degrees. What is the coefficient of static friction
