Alarge air reservoir supplies (k = 1.4 and rair = 287 n m / kg. k) a convergent nozzle that discharges at atmospheric pressure (patm = 101 kpa). assuming that the flow is reversible and adiabatic inside the nozzle, determine: if the pressure in the tank is 600 kpa (abs) and the temperature is 600k, what is the mass flow through the nozzle if the output area is 1.29x10^-3 m²?

If a particle moves along a path such that r : (3 sin t) m and ? : 2t rad, where t is in seconds. what is the particle's acceleration in m/s in 4 seconds? a)- 16.43 b)- 16.29 c)- 15.21 d)- 13.79

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.

What are the major differences between injection molding and extrusion?
