One cubic meter of water (see Table 4.4 for the mass density of water) flowing over the Lower Falls in Yellowstone National Park drops
94 m.
If all of the water's potential energy is converted to kinetic energy at the bottom of the falls and the kinetic energy goes to heat the water, what is the temperature increase of the water?
Homework Answers
The volume of the water is
The density of water is
So, the mass of the given volume of water is
The potential energy at the top of the fall is
The specific heat of the water is
So, the change in the temperature is
So, the change in temperature is 0.22 oC.

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

A fluid of constant density (p) at 40 °F (T) is flowing into an initially empty cylindrical tank of radius 10 ft. The cylindrical vešsel is jacketed and heated with saturated steam (T) at 212 °F.The steam jacket does not cover either the top or bottom of the tank. The heat capacity of liquid (Cp liquid is near to that of water. The vessel is well stirred and the heat resistance of the jacket is negligible as are the heat...
