An incompressible fluid enters the left pipe with a velocity of 2.5 [m/s]. Part of the fluid streams fills anoverflow tank, which has an initial height of 30 [cm], and the other part exits to the right with a velocity of1.9 [m/s]. Estimate how long it takes for the fluid in the tank to reach a level of 100 [cm].

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
