The main water line enters a house on the first floor. the line has a gauge pressure of 2.64 x 105 pa.

(a) a faucet on the second floor, 6.50 m above the first floor is turned off. what is the gauge pressure at this faucet?

(b) how high could a faucet be before no water would flow from it, even if the faucet were open?

a. P1=200235pa

b. h=26.91m

Explanation:

The main water line enters a house on the first floor. The line has a gauge pressure of 2.64 x 105 Pa.

(a) A faucet on the second floor, 6.50 m above the first floor is turned off. What is the gauge pressure at this faucet?

(b) How high could a faucet be before no water would flow from it, even if the faucet were open?

pressure is the force per unit area.

force is that which tends to change a boy's state of rest or uniform motion in a straight line

rho stands for the density of water which is 1000kg/m3

p2=p1+rhogh

p1=p2-rhogh

the gauge pressure at 6.5m

will be:

2.64 x 10^5 Pa-100kg/m3*9.81*6.5

P1=200235pa

b. How high could a faucet be before no water would flow from it, even if the faucet were open?

b.h=p2-p1/(grho)

h=2.64 x 105 Pa/(1000*9.81)

h=26.91m
