A 9-cm-diameter vertical water jet is injected upward by a nozzle at a speed of 15 m/s. Determine the maximum weight of a flat plate that can be supported by this water jet at a height of 2 m from the nozzle. Take the density of water to be 1000 kg/m3. The maximum weight of a flat plate that can be supported by the water jet is ____ N

A vertical wheel with a diameter of 39 cm starts from rest and rotates with a constant angular acceleration of 7.2 rad/s2 around a fixed axis through its center counterclockwise. a) Through what angle (in degrees) has the point initially at the bottom of the wheel traveled when t = 14 s? (Indicate the direction with the sign of your answer.) b) What is the point's total linear acceleration at this instant? (Enter the magnitude in m/s2.

Water at 15°C enters a tube of 2 cm of diameter with flow rate 3953 kg/h. Assume the ratio L/D >10, and the wall temperature is constant at 80◦C. The outlet temperature is 50°C The properties of water at the film temperature are density rho = ? = 985 ?/?3, specific heat ?p = 4180 ?/?, conductivity ? = 0.651 ?/?, dynamic viscosity mu= ?? = 4.71 × 10−4 ?/?, At the wall temperature of 80°C we have dynamic viscosity...

1.) The femur of an elephant is about 90 cm long and 15 cm in diameter. This is a scaling problem. The largest dinosaur probably weighed about 10 times as much as a large elephant. In this problem we will be discussing scaling. For reference, areas scale as length squared(A=L^2 for a square and A=3.14*r^2 for a circle) and volume scales as length cubed. To describe the size of a dinosaur's femur compared to that of an elephant's, the dinosaur's...

A jet of water 50 mm in diameter with a velocity of 20 m/s strikes a flat plate inclined at an angle of 30° to the axis of the jet. Determine (i) the normal force exerted on the plate when the plate is stationary (ii) the normal force exerted on the plate when the plate is moving at 5 m/s in the direction of the jet (iii) the work-done on the plate and the efficiency for case (ii).

Water at 298 K discharges from a nozzle and travels horizontally, hitting a flat, vertical wall.

(Problem 4.3-3) Water at 298 K discharges from a nozzle and travels horizontally, hitting a flat, vertical wall. The nozzle has a diameter of 12 mm and the water leaves the nozzle with a flat velocity profile at a velocity of 6.0 m/s. Neglecting frictional resistance of the air on the jet, calculate the force in newtons on the wall. Ans. –Rx = 4.059 N Repeat Problem 4.3-3 for the same conditions except that the wall is inclined 45°...

Water drips from the nozzle of a shower onto the floor 200 cm below. The drops fall at regular (equal) intervals of time, the first drop striking the floor at the instant the fourth drop begins to fall. Find the locations (above the floor in cm) of the second and third drops when the first strikes the floor. Second drop? Third drop?

Water drips from the nozzle of a shower onto the floor 181 cm below. The drops fall at regular (equal) intervals of time, the first drop striking the floor at the instant the fourth drop begins to fall. When the first drop strikes the floor, how far below the nozzle are the (a) second and (b) third drops?

A drinking fountain shoots water about 14 cm up in the air from a nozzle of diameter 0.60 cm. The pump at the base of the unit (1.1 m below the nozzle) pushes water into 1.2 cm diameter supply pipe that goes up to the nozzle. What gauge pressure does the pump have to provide? Ignore the viscosity; your answer will therefore be an underestimate

A circular coil with a diameter of 25.0 cm and 158 turns rotates about a vertical axis with an angular speed of 1230 rpm . The only magnetic field in this system is that of the Earth. At the location of the coil, the horizontal component of the magnetic field is 3.81×10−5T, and the vertical component is 2.85×10−5T. Find the maximum emf induced in the coil. Answer in mV
