A Water Line Enters a House 2

A water line enters a house 2.0 m below ground.A smaller diameter pipe carries water to a faucet 5.0 m above ground, on the second floor.Water flows at 2.0 m/s in the main line and at 7.0 m/s on the second floor.Take the density of water to be 1.0 x10³ kg/m³.The pressure in the main line is 2.0 x 10⁵ Pa; then the difference in pressure between the main line and the second floor is:

A) 6.9 x 10⁴ Pa with the main line at the higher pressure
B) 2.3x10⁴ Pa with the main line at the higher pressure
C) 6.9x 10⁴ Pa with the main line at the lower pressure
D) 2.3 x 10⁴ Pa with the main line at the lower pressure
E) 9.1 x10⁴ Pa with the main line at the higher pressure
