Homework Help: Fluid and heat transfer in a hot water heater

  1. Aug 26, 2009 #1
    Please help me with this :

    1) Water circulates throughout a house in a hotwater heating system. The water is pumped at a speed of .7 m/s through a 4 cm diameter pipe in the basement under a pressure of 3 atm. What is the pressure, to the nearest N/m^2, in a 2 cm pipe on the second floor 5 meters above the basement?

    2)If the basement pipe is 4 cm in diameter and the water velocity is .8 m/s, what is the flux of the outflow, to the nearest tenth, of a liter/s at a 0.84 cm diameter faucet on the second floor?

    Re: Fluids

    Use the equation for volume flow continuity (A1v1=A2v2) and Bernoulli's equation.

    Give it a shot and show us what you did.
