Water circulates through a hot-water heating system in a house. The water leaves the basement with a speed of 0.5 m/s through a 4-cm-diameter pipe, under a total pressure of 3Patm. (Assume that all the pipes have circular cross-sectional areas and that the pipes don't "branch off" at any point.) a) If the pipe on the second floor of the house has a smaller radius than the basement pipe, will the speed of the water in the second-floor pipe be...

There is a pipe with a radius of 47 cm. Water is flowing thorugh this pipe and ends up 4.7 m below the starting point with a radius of 83 cm. The water enters at the starting point with a velcity of 4.9 m/s. What is the pressure difference between the starting point and endpoint of the pipe assuming that the density of water is 1000 kg/m^3.
