8. [-/1 Points) DETAILS SERCP119.7.P.037. MY NOTES ASK YOUR TEACHER A hypodermic syringe contains a medicine with the density of water (figure below). The barrel of the syringe has a cross-sectional area of 2.67 x 10-5 m2. In the absence of a force on the plunger, the pressure everywhere is 1.00 atm. A force i of magnitude 1.79 N is exerted on the plunger, making medicine squirt from the needle. Determine the medicine's flow speed through the needle. Assume the...

Sheba, the American Pit Bull Terrier, runs and jumps off the dock with an initial speed of 9.12 m/s at an angle of 22° with respect to the surface of the water. (Assume that the +x axis is in the direction of the run and the +y axis is up.) (a)...

1. Atall cylindrical tank, held above ground on stilts, is partially filled with water. (See top figure). The tank has a diameter, D. At time equal to zero, a hole of diameter d is poked in the bottom of the tank, where d<< D. Let z-0 correspond to the bottom of the tank. The initial fluid height is za. Had Use Bernoulli equation to assess the velocity of the fluid as it leaves the bottom of the tank as a...
L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
