1.From a point 1, a 25mm diameter pipe runs horizontally under the floor and then a 12.5 mm diameter line runs 1 m up the wall to a point 2. To maintain a pressure of 300kPa at point 2, what the 15 C water is flowing at 0.5 L/s, what pressure must be provided at point 1 if you neglect friction?
2.A pressure gage at elevation 4.8 m on the side of a storage tank containing oil reads 34.7 kPa.Another gage at elevation 2.2 m reads 57.5 kPa. Compute the specific weight, density, and specific gravity of the oil.
Block A, 5lb, strikes block B, 10lb. Block A is moving with the intial velocity, Va, and block B is at rest. After striking block B, block A travels 2 in. to the right and block B travels 3 in. to the right.
calculate the alkalinity as CaC03 of water that contains 85mg/l of HCO3, 120 mg/l of CO3 and 2 m/l of OH.
A canal of rectangular cross-section and an n=0.030 is to be laid on a slope of 0.002 and is to carry a discharge of 30 m3/s. Calculate the cross-sectional area required for the channel to carry this flow based on the norma
Input parameters for the function should be the lower and upper bounds of the root. Obtain reasonable values for the lower and upper bounds by graphing the function in Excel. Turn in your code for the VBA function.
A nylon thread is to be subjected to a 10-N tension. Knowing that E=3.2 GPa, that the maximum allowable normal stress is 40 MPA, and that the length of the thread must not increase by more than 1%, determine the required diameter of the thread.
The electric pole and the stub pole are at the edges of the roadway right-of-way. The anchor will be outside of the right-of-way and will require the subdivision to purchase land from the neighbouring farmer (who is VERY UNHAPPY about the subdivis..
A very long rectangular channel connects two reservoirs and has a longitudinal slope of 0.005. The channel has a width of 10 m and a Manning's n of 0.030.
The number of flaws on a sheet of aluminum manufactured by a certain process follows a Poisson distribution. In a sample of 100m2 of aluminum, 200 flaws are counted.
Cooling at constant pressure followed by heating at constant volume. Calculate Q, W, change in U, and change in H for each of these processes, and sketch the paths of all processes on a single PV diagram.
how far back from the front axle would the center of gravity have to be to ensure that the maximum tractive effort developed for front- and rear- wheel-drive options is equal (assume that all other variables are unchanged)
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
It is possible to produce cast irons that consist of a martensite matrix in which graphite is embedded in either flake, nodule, or rosette form. Briefly describe the treatment necessary to produce
