If an object is moved a distance D in the direction of an applied constant force F, then the work W done by the force is defined as W= FD If an object is moved along a straight line by a continuously varying force F(x) then the work W done by the force as the object moved from x=a to x=b is W =S° F (x)dx Work as the summation of increments are, AW = force (Distance Increments) = F(Ax) and AW = force Increments (Distance) F(Ax). Solve with solution: 1. Determine the work done by lifting a 150-lb object 4 feet.

The pressure in a water tower is 20,674 Pascals (N/m2) higher than at an open faucet. The density of water is 1000 Kg/m3. Use Bernoulli’s equation to determine the velocity of outflow from the open faucet. If the height difference between the top water level in the tower and the faucet is 7.2 meters, then the velocity of outflow is ROUND TO 3 DECIMAL PLACES
Please help me with this fluid mechanics question! Thank you!! :) A 1967 Harley-Davidson Shovelhead motorcycle uses a ventruri-carburetor to mix air and fuel for combustion. The venturi reduces the pressure to draw fuel from a reservoir chamber and to mix with the airstream as shown in the figure. The energy loss of the metering line is given by hL= (K*V^2)/2where K = 6.0 and V is the fuel velocity in the metering line. Assume that the air is an ideal fluid (68°F). Calculate the mass flux of air and the mass flux of fuel. Hint: Assume the air intake velocity is negligible.
Experiment #2: Acceleration vs. Mass Link https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion-basics_en.html In this lab you will determine the relationship between acceleration and mass. Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)
