Reconsider Prob. 16-45. Using EES (or other) software, study the effect of the final temperature on the rate of heat supplied for the two cases. Let the final temperature vary from 2500 to 3500 K. For each of the two cases, plot the rate of heat supplied as a function final temperature.
Prob. 16-45
Water vapor (H2O) is heated during a steady-flow process at 1 atm from 298 to 3000 K at a rate of 0.2 kg/min. Determine the rate of heat supply needed during this process, assuming (a) some H2O dissociates into H2, O2, and OH and (b) no dissociation takes place.
A 0.75 m high rectangular sharp-crested weir extends across a 2.2m wide rectangular channel. When the head is 32 cm, determine the flow rate
Water at a pressure of 13 atm, at street level, flows into a building at 3m/s through a 6 cm diameter pipe. The pipe tapers down to a 2 cm diameter by the top floor 50 m above.
determine the correspondig angular acceleration alpha of the beam, the acceleration of C, and the distance b from B to a point P on the beam centerline which has no acceleration
Car moving 54 km/h when light is 240 m away turns red. Light stays red for 24 seconds. If the motorist wishes to pass the light just as it turns green without having to stop, what is the required uniform deceleration of the car and what is the speed ..
A 2 m high sandy fill material was placed loosely at a relative density of 47%. Laboratory studies indicated tht the maximum and minimum void ratios of the fill material are 0.92 and 0.53, respectively.
A subsurface detention basin is installed beneath a street to help prevent flooding. Water from the rain is chanelled into the basin and begins to infiltrate into the ground when it reaches 1ft.
The pins on the frame at B and C each have a diameter of 0.25 in. If these pins are subjected to double shear, determine the average shear stress in each pin.
Two pipes of identical length and material are connected in parallel. The diameter of one is twice the diameter of the other. What is the ratio of the flow rates (Q2/Q1) in the two pipes
A constant-head permeability test was conducted on a sample of fine silica sand. The cross-sectional area of the sample was 60 cm2 and its length was 150 mm.
The settlement analysis for a proposed structure indicates that 6cm of settlement will occur in 4 yr and that the ultimate total settlement will be about 25cm. the analysis is based on the assumption that the compressible clay layer is drained at bot..
For a given load increment, the time for 50% consolidation was 5 min 20 sec. How long will it take for 50 % consolidation of a similar clay layer in the field that is 8.2 ft thick & drained on one side only
When stationary, vehicles are spaced at average distance headway of 6 m. It may be assumed that there is a linear relationship between speed and density. When the traffic flow approaching the roadworks is 3500 vehicles per hour
