Find how 1 g of chlorobenzene and 1 g of hexachlorobenzene distribute into an environment at 25 °C containing the following phases (all are present in the system and consider only equilibrium). 1 L of water containing 100 mg/L dissolved organic carbon
1 kg (dry)MM of soil containing 1% organic carbon
1 L of air
a. Consider no NAPL present- Is this possible?
b. Consider 10 mL of an oily aromatic solvent (ρ=0.8g/cm3 , rMW 100 g/mole) in which both chlorobenzene and hexachlorobenzene form an ideal phase. This is in addition to the phases identified above.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
