The storage tank of a water tower is a vertical cylinder of diameter D = 7 m, the initial depth of water within it is ho =6 m and the free surface is exposed to the atmosphere.
The flywheel of a small punching machine rotates at 360 rpm. Each punching operation requires 1500 ft-lb of work and it is desired that the speed of the flywheel after each punching be not less than
A 500-hp hydroelectric plant generates power using water at a rate of 1000 ft^2/min with an overall efficiency of 35%. What is the minimum height of the water in units of ft?
Calculate (1) the final volume of the system, (2) the work done by the system, (3) the heat entering or leaving the system, (4) the change in the internal energy.
Assume the pressure in the air above the water was 40 kPa absolute, and the temperature of the water was 15 degrees Celsius. The cylinder was 0.70 meters long.
Without transforming the data use fminsearch to estimate C1 and C2. Plot the data and the two fits on the same graph. Be sure to use a legend to identify the fits.
The exit mass flowrate during this condition is constant at 20 kg/s. Find the elapsed time from when the relief valve first opens to the point when the water level drops below the top of the core.
