The velocity of air in the diverging pipe shown in Fig. P4.26 is given by (V_{1}=4 t

Question:

The velocity of air in the diverging pipe shown in Fig. P4.26 is given by \(V_{1}=4 t \mathrm{ft} / \mathrm{s}\) and \(V_{2}=2 t \mathrm{ft} / \mathrm{s}\), where \(t\) is in seconds.

(a) Determine the local acceleration at points (1) and (2).

(b) Is the average convective acceleration between these two points negative, zero, or positive? Explain.
