8.16 a 0.5 mhz antenna carried by an airplane flying over the ocean surface generates a wave that approaches the water surface in the form of a normally incident plane wave with an electric-field amplitude of 3,000 (v/m). seawater is characterized by r = 72, Ī¼r = 1, and Ļƒ = 4 (s/m). the plane is trying to communicate a message to a submarine submerged at a depth d belowthewater surface. if the submarineā€™s receiver requires a minimum signal amplitude of 0.01 (Ī¼v/m), what is the maximum depth d to which successful communication is still possible?

Water at 70Ā°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.
