Water is pumped from a lower chamber to a higher chamber by a pump driven by a 55 kW electric motor with an efficiency of 85%. The free surface of the upper chamber (open surface to the atmosphere) is 75 m higher than the free surface of the chamber below. The free surface velocities are negligible. The magnitude of the gravitational acceleration is given as 9.81 m/s^2. Since the mass flow rate of the water is 50 kg/s, calculate the mechanical power loss in kW during the upward transfer of the water. 1.665 9.96 18.21 3.21 12.45 5.70

Answer the following questions about air flowing through a nozzle as shown in the schematic below. The air enters the nozzle at 2.2 kg/m³ and 34 m/s and leaves at 0.72 kg/m³ and 130 m/s. The nozzle inlet area is 60 cm². The mass flow rate is 4.5 kg/s. The outlet cross-sectional area is 1 cm². P1 Nozzle V₂ P2
A fan delivers 283.2 m³ / min of air with a density of 1.2 kg/m³ through a duct 5.08 cm by 5.08 cm at the static pressure of 2.3 cm WG. If the power input to the fan is measured as 2.70 kW, determine; (a) the air velocity, m/sec (b) the total head if the velocity head is 8.2 meters (c) the mechanical efficiency of the fan.
Consider a wind turbine that is situated in an area that has steady winds. The turbine rotates at 16 RPM. The mass flow rate through the turbine is 41,025 kg/s. The tip velocity is 260 km/hr. Take the air density to be 1.31 kg/m² and assume 180kW of electric power is generated by the turbine. Determine the following: a. Average velocity of the air b. The efficiency of the turbine c. Assuming winds are steady for 95% of the year, is this a suitable location for a wind turbine? Explain.
Two parallel shafts whose centers are 10 meters apart are connected by an open belt drive with a V-belt with a groove angle of 30°. The diameter of the larger pulley is 1000 mm and that of the smaller pulley is 400 mm. The smaller pulley is running at 1000 rpm to deliver 10 kW of power. The mass of the belt is 1 kg/m. Taking centrifugal tension into account, determine the minimal cross-sectional area if the allowable tensile stress of the belt is 5 MPa. The coefficient of friction between the belt and the pulleys is 0.25.
A site is being considered for wind power generation. At this site, the wind blows steadily at 9 m/s for 2,579 hours per year. Assuming the wind velocity is negligible at other times for simplicity, determine the kWh/year that can be produced at the site for a turbine with a mechanical efficiency of 100% and an effective flow area of 5 m2. Use a value of 1.25 kg/m3 for the density of the air. Give your answer in killowatt-hours per year (kWh/year). Hint: I reccomend starting by finding the kinetic energy (kJ/kg) of the wind. Hint 2: Multiply the power generation (kW) by the number of hours of wind per year (h/year) to get kWh/year.
A slingshot, which can be modeled as a spring with spring constant k = 81.9 N/m, is stretched by 22 cm with respect to its equilibrium position and used to shoot a rock with mass 0.09 kg straight up into the air. Find the speed of the rock (in m/s) when it reaches a height which is 25% of its maximum height (relative to the position at which it was shot from). Use g = 9.81 m/s?. Hint: First find the maximum height, and then find the speed when the height is 25% of that.

An oil-transfer pump uses 1 kW of power in transferring 5 kg/s of oil through a 3-cm-diameter pipe. The changes in kinetic and potential energies are essentially zero, and the process is adiabatic. Additionally, there is no appreciable temperature change in the oil, which has a density of 1500 kg/m³. Determine the change in pressure from inlet to exit.
1) Air with a density of 0.45 kg/m3 enters an experimental jet engine at a rate of 175 m/s. The inlet area of the engine is 7.0 ft2. After fuel is burned, the air and combustion byproducts leave the engine with a velocity of 695 m/s through an outlet area of 6.0 ft2. What is the average density of the gas exiting the engine? Express your answer in kg/m3, slugs/ft3, and lbm/ft3. 2) Calculate the mass moment of inertia of the thin ring shown in the accompanying diagram. Express your answer in lbm · ft2, lbm · in2, and slugs · ft2. (Assume the axis of rotation is into the page through the center of the ring.) m = 0.8 slugs radius is 9 in.

A fan is to be selected to ventilate a bathroom whose dimensions are 2 m × 3 m × 3 m. The air velocity is not to exceed 7 m/s to minimize vibration and noise. The combined efficiency of the fan–motor unit to be used can be taken to be 50 percent. If the fan is to replace the entire volume of air in 15 min, determine (a) the wattage of the fan–motor unit to be purchased, (b) the diameter of the fan casing, and (c) the pressure difference across the fan. Take the air density to be 1.25 kg/m3 and disregard the effect of the kinetic energy correction factors.
