Determine the mass flow rate of R-134a and the power input to the compressor. Use data from the refrigerant tables. Heat transfer with the surroundings is negligible. Neglect kinetic and potential energy changes. (Round the final answers to three decimal places.)

A property owner on a lake is given an aluminum dock for his property. Unfortunately the dock
is too large and heavy to move over land. Instead the owner has this idea (which his family
thinks is insane) to move the dock by water. The dock is 20 ft long, 3ft wide, and weighs 350 lbs.
The owner decides to float the dock using 50 gallon plastic drums filled with air.
a) (5 points) How many 50 gallon drums are required to float the dock?
b) (3 points) How many would you recommend the home owner actually use and in what
configuration? Why?
A large water tank is being filled from a water source as shown in the figure below with a
desired flow rate of 20 L/min.

d) (2 Points) If the pump is 93% efficient, how much power must be supplied to the pump?
e) (2 Points) If we considered minor losses, would it take more time, less time or the same
amount of time to fill the tank? Explain why (in words, no math)

Barrow_forwardAs indicated by the derivation, the principle of work and energy is valid for observers in any inertial reference frame. Show that this is so, by considering the 10-kg block which rests on the smooth surface and is subjected to a horizontal force of 6 N. If observer A is in a fixed frame x, determine the final speed of the block if it has an initial speed of 5 m/s and travels 10 m, both directed to the right and measured from the fixed frame. Compare the result with that obtained by an observer B, attached to the x' axis and moving at a constant velocity of 2 m/s relative to A. Hint: The distance the block travels will first have to be computed for observer B before applying the principle of work and energy.
