A rigid, insulated vessel contains superheated vapor steam at 3 MPa, 400?C. A valve on the vessel is opened, allowing steam to escape, as shown in Fig. P6.57. The overall process is irreversible, but the steam remaining inside the vessel goes through a reversible adiabatic expansion. Determine the fraction of steam that has escaped when the final state inside is saturated vapor.
The tank material is such that it can withsatand tension caused by a volume expansion of 2%. Determine the max temperature rise in Celcius degress allowed without jeopardizing safety.
Find the area of steel reinforcement required for a concrete T-beam for the following data; f'c = 3 ksi, fy=50 ksi,d=28 in, t= 6 in., bw= 16 in., bf= 60 in., and the section sustains a factored bending moment of Mu=360 kip ft

Two new rides are being compared by a local amusement park in terms of their annual operating costs. The two rides are assumed to be able to generate the same level of revenue (and thus the focus on costs). The Tummy Tugger has fixed costs of $10,000..
To imagine the diagram, the collar at point A (unstretched) is on the same x-axis as the anchor @ C, while the collar point B (stretched) is located downwards-left to point A, forming a 30 degree angle with the y-axis (vertical). In other words, the ..
