Leah is sitting on of her surfboard out in the ocean. She is waiting for the perfect wave to come along so she can ride it in to
shore. As she waits, she notices that the waves roll by in patterns, or sets.
As Leah its, she counts the number of waves that pass her during a 10-second period; she counts just 1. She estimates that the
distance between crests is 6 meters. Betty sees the perfect wave and begins paddling. She pushes herself up, stands on the
surfboard and rides the wave all the way in to shore, a distance of about 60 meters. It takes her about 10 seconds to ride the
wave in. Use two methods to calculate the speed of the wave based on the information presented. Are they the same? Explain
how you got your answers.

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
