1) An inviscid flow passes through a 2-D channel, followed by a 2-D diffuser as shown. The channel and the diffuser are both L long, and the exit area ratio of the diffuser, AR, is given by the exit area (W2) divided by the inlet are of the channel (W₁) such that AR = W₂/W₁. The channel inlet velocity increases as V₁ = V (+) for 0 < t≤ to. Determine the pressure ratio, P2-P1 Ср = 1 pvz as a function of time, t. V₁-> Diffuser area ratio AR-W2/W₁ X L L
