1. A hypodermic syringe contains a medicine with a density of water. The barrel of the syringe has a cross-sectional area of 2.5x10e-5 m^2. A force of 2N is exerted on the pluger (left, larger side). Determine the velocity of the medicine as it emerges from the needle _________ \ \ (1) (2)===== / _________/ 2. P1 + 1/2pV1^2 + pghi = P2 + 1/2pV2^2 + pghf Area = 2.5x10e-5 m^s, Force = 2 N P1 = F/A = 80,000 Pascals Because Area decreases, Velocity increases decreasing pressure so we assume P2 = 0, is this correct why we make P2 = 0?
