Products of combustion enter a gas turbine with a stagnation pressure of 1.0 MPa and a stagnation temperature of 750°C, and they expand to a stagnation pressure of 100 kPa. Taking k = 1.33 and R = 0.287 kJ/kg · K for the products of combustion, and assuming the expansion process to be isentropic, determine the power output of the turbine per unit mass flow.
A toxic compound being is removed from solution in a CSTR at Steady State according to a first order reaction rate. The upstream concentration of the pollutant is 14 mg/L and the downstream concentration is 1.7 mg/L.
A 0.3 meter cubed rigid tank is filled with saturated liquid water at 200 degrees Celsius. A valve at the bottom of the tan is opened and liquid is withdrawn from the tank. Heat is transferred to the water such that the temperature in the tank remain..
A structural element subjected to cyclic loading is made of fc' = 3000 psi concrete. Compressive stresses are changing between 2200 psi and 1600 psi. The frequency of loading is 8 Hz.
Thomas Friedman's bestseller, The World is Flat, says that the world has been, in his words, "flattened" or leveled which increases accessibility and competition worldwide. What does this mean for engineering and for managers who deal with enginee..
The company would like to distribute the songs between the two CDs such that the used space on each CD is about the same. Formulate the problem as an IP, and find the optimal solution.
A water treatment plant uses a dual media filter. The two media used are: a) Anthracite coal with effective diameter of 1.1 mm, porosity of 0.6, and shape factor of 0.5. b) Sand with effective diameter of 0.5 mm, porosity of 0.45, and shape factor of..
Design Span S2 of the continuous one-way slab example (we designed Span Si in class). Use ACI coefficients. The slab is to support a service live load of 170 psf in addition to its own weight. fc' = 3,000 psi and fy= 40,000 psi. The slab is to be ..
What are the three meterials based on the predominant types of bond and what are the predominant types of bond in each category?
At a pumped storage facility, water is pumped from a large reservoir to a point 150 feet above the resevoir. How many feet of head must the pump add to achieve 10,000 lbm/hr flow through a 24 inch pipe with a friction head loss of 1.5 feet
How much of a reduction in the automobile emission rate would be required to achieve the maximum eight-hour average NAAQS for CO at steady state 9 ppmv ( (10.3 mg/m^3)?
A 440 -V shunt motor has armature resistance of 0.8 ohm and field resistance of 200 ohm . determine the back emf when giving an output of 7.64 KW at 85% efficiency
A 900-mm strip of steel is bent into a full circle by two couples applied. Determine (a) the maximum thickness t of the strip if the allowable stress of the steel is 420 MPa, (b) the corresponding moment M of the couples.
