You are supposed to pick up food with sizes ranging from 0.5 in (blueberries) to 2 in (strawberries). Use the salad tongs dimensions given in the first page to determine the maximum normal stress (due to bending) in the salad tongs when picking blueberries and strawberries. Your expressions should still be a function of the elasticity modulus E, since you have not yet selected the material of your salad tongs. Can you tell which food (blueberry or strawberry) will cause the higher stress, regardless of the material selection

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
