Consider water flow through a horizontal, short garden hose at a rate of 30 kg/min. The velocity at the inlet is 1.5 m/s and that at the outlet is 14.5 m/s. Disregard the weight of the hose and water. Taking the momentum-flux correction factor to be 1.04 at both the inlet and the outlet, the anchoring force required to hold the hose in place is (a) 2.8 N (b) 8.6 N (c) 17.5 N (d) 27.9 N (e) 43.3 N

Consider water flow through a horizontal, short garden hose at a rate of 30 kg/min. The velocity at the inlet is 1.3 m/s and that at the outlet is 11.75 m/s. The hose makes a 180° turn before the water is discharged. Disregard the weight of the hose and water. Taking the momentum-flux correction factor to be 1.08 at both the inlet and the outlet, the anchoring force (in N; hint: the answer is a negative number) required to hold the hose in place is ?

A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3. Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.

Hello Sir.Good Night I have a question in my homework related chemical material lesson. The following below is my question.Please advice, thank you. "Explain the stages of the metal strengthening process ?"

not an assingment or assesed question its a tutorial

When is the conservation of linear momentum often applied?

Water is flowing through a 15-cm-diameter pipe that consists of a 3-m-long vertical and 2-m-long horizontal section with a 90° elbow at the exit to force the water to be discharged downward, as shown in Fig. P6–55, in the vertical direction. Water discharges to atmospheric air at a velocity of 5 m/s, and the mass of the pipe section when filled with water is 17 kg per meter length. Determine the moment acting at the intersection of the vertical and horizontal sections of the pipe (point A). What would your answer be if the flow were discharged upward instead of downward?

A vehicle travelling at 100 km/h has air passing through its radiator at the rate of 100 kg mol per minute. The hot water from cooling the engine is circulated through the radiator at the rate of 10 L per minute, and as it passes through the radiator it is cooled from 78 °C to 32 °C. Assume the car is in good condition so the radiator has no leaks and the air and water do not contact. Given the heat capacity of the air is 1.0035 J·g-1·K-1, what is the temperature of the air exiting the radiator (assume air has a molecular weight of 29 g·mol-1).

A horizontal pipe has an abrupt expansion from D1 = 8 cm to D2 = 16 cm. The water velocity in the smaller section is 10 m/s and the flow is turbulent. The pressure in the smaller section is P1 = 410 kPa. Taking the kinetic energy correction factor to be 1.06 at both the inlet and the outlet, determine the downstream pressure P2, and estimate the error that would have occurred if Bernoulli’s equation had been used.

Consider a wind turbine with a 90 m blade span subjected to steady wind is used to generate electric power. The combined turbine generator efficiency of the wind turbine is 30 percent. If the horizontal force exerted by the wind on the supporting mast is 100 + 64  KN.  Determine (a) the wind velocity and (b) the power generated by the turbine. Take the density of air to be 1.25 kg/m3, and disregard frictional effects.
