You are taking a shower in your dormitory when someone flushes a toilet nearby. The pressure in the cold water line drops and you find yourself showering in what feels like molten lava. This loss of cold water pressure occurs when the flushing toilet lets more cold water flow through the pipes delivering it to the bathroom and the water's speed in those pipes increases. The cold water's faster motion in the delivery pipes reduces its pressure in the shower head because faster moving water
A. has less pressure than slower moving water.
B. has less kinetic energy than slower moving water.
C. has less gravitational potential energy than slower moving water.
D. losses more energy to viscous drag as it flows through the delivery pipes.
