Compare the path loss in dB for two possible cellular environments where there is (1) free
space between mobiles and base stations, and (2) urban area cellular radio with n = 3.1. Use 1.9 GHz at a
distance of 1.5 km and assume isotropic antennas.
Hint: LdB = 20 log(f) + 10n log(d) − 147.56dB

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
