Aship on the surface of the ocean receives a sonar echo back from an underwater object. the echo path from the object to the ship is at an angle of 35 degrees above the horizontal and takes 3s to return. (velocity of sound in sea water = 1500m/s). a) what is the distance of the object from the ship? b) what is the depth of the object in the sea?

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
