Helium enters an adiabatic steady-state nozzle at 200kPa and 124 degrees Celsius and 10m/s. At the nozzle exit the temperature of the helium is 100 degrees Celsius and the pressure = 150 kPa.
1) Determine the velocity of the steam at the nozzle outlet.
a) 100 m/s b) 200 m/s c) 400 m/s d) 500 m/s
2) The nozzle process specifide is: (explain)
a)Reversible and adiabatic
b) Reversible because the generated entropy in the surroundings = 0
c) Impossible because the entropy of helium decreases
d) Irreversible because the entropy of helium increases
A composite beam is made by attaching the timber and steel portions shown with bolts of 14-mm diameter spaced logitudinally every 200 mm. The modulous of elasticity is 10 GPa for the wood and 180 GPa for the steel
A wide alluvial stream carries water with a mean depth of 1 m and slope of 0.0005. The mean diameter of the bed material is 0.5 m with a density of 2650 kg/m^3. Examine the stability of the bed.
Calculate the overall modulus of the composite, explaining your calculations and the assumptions you have made when it is loaded:
A haul fleet of trucks having a heaped capacity of 15 cy. is to be loaded by a hydraulic backhoe excavator (CT=.48 min.) with a 3 1/2 cy. heaped capacity. Assume the material is a wet loam that weighs 3380 lb/cy in the bank state
determine the factor of safety against overturning about point a if 3 .the factor of safety is defined as the ratio of
Two pumping wells 1,000 m away fully penetrate the same confined aquifer. One of the wells pumps at a rate of 1240 m3/ day and the second well pumps at 850 m3/ day.
To apply shock loading to an artillery shell, a 20-kg pendulum A is released from a known hight and strikes impactor B at a known velocity Vo. inpactor B then strikes the 1-kg artillery shell C.
For a given hypothetical flow, the velocity from time t=0 to t=5s was u=3m/s, v=3m/s. then from time t=5s to t=10s, the velocity was u=2m/s, v=2m/s. A dye streak was started at a point in the flow
Starting from x = 0 with no initial velocity, the acceleration of a race car is defined by the relation a = 6.8e- 0.00057x , where a and x are expressed in m/s 2 and meters, respectively. Determine the position of the race car when v = 30 m/s.
Each wheel of an automobile has a weight of 48 lb, a diameter of 23 in., and a radius of gyration of 9 in. The automobile travels around an unbanked curve of radius 450 ft at a speed of 65 mi/h.
a wind tunnel is used to experimentally determine the lift force L and drag force D on a scale model of an aircraft. the bracket supporting the aircraft is fitted with an axial spring with stiffness k= 0.125 N/mm and a torsional spring with stiffn..
A single crystal of a FCC metal is oriented so that the [001] direction is parallel to an applied stress of 35.0 MPa. Calculate the resolved shear stress acting on the (111) slip plane in the [110], [0-11], [10-1] slip directions.
