K.C.S.E Physics Q & A - MODEL 1999PP1QN25

Figure 13 shows a section of a pipe PQ. A constant pressure difference maintains a streamline flow of a liquid in the pipe

If the cross-sectional area A1 at P is less than A2 at Q, state how the liquid velocity. V2 at Q compares with velocity V1 at P.

ANSWER

• V2 is smaller than V1                           
•  V1 is larger than V2
