Solve the differential equation
to find the value of X(0.25) using the Euler method with steps of size 0.05 and 0.025. By comparing the two estimates of x(0.25) estimate the accuracy of the better of the two values which you have obtained and also the step size you would need to use in order to calculate an estimate of x(0.25) accurate to three decimal places.
In an ore minig operation, a bucket full of ore is suspended from a traveling crane which moves slowly along a stationary bridge. The bucket is to swing no more than 4m horizontally when the crane is brought to a sudden stop. Determine the maximum..

Determine the turbine inlet temperature, the cycle thermal efficiency, and the back-work ratio of this cycle.
Consider the pipe and Venturi meter system shown in the three figures at a angle of 30° to the horizontal. The pipe and the Venturi meter in all three systems are identical, but the means of measuring the piezometric head (or pressure head) are diffe..
Consider a material composed of equal volumes having different yield strengths, YB = 1.5YA, but the same elastic moduli, EA = EB. Assume that during strain- ing both regions undergo the same strains (εA = εB ) and that there is no strain- hardening i..
A piston-cylinder device contains 1.0 kg of liquid water and 0.01 kg of water vapor (steam) in equilibrium at 7 bars. The pressure is held constant and heat is added until the temperature reaches 280 C.
Describe IN DETAIL how you could determine the required rate of heat addition or removal.
Saturated Steam is to be condensed on the shell side of a heat exchanger at 75°F. Cooling water enters the tubes at 50°F at a rate of 45 lbm/s and leaves at 65°F. Assuming the heat exchanger to be well-insulated, determine the rate of heat transfer i..
