Determine the power generated by the turbine (in KW) operating in steady state at 5MPa, with specific enthalpy 3000kj/kg and velocity of 10m/s at the entrance and steam escaping at 0.07MPa, specific enthalpy 2000kj/kg at velocity of 90m/s p. The inlet is located 1m above the outlet and mass flow rate is 11kg/s.
A pump is to be used to draw seawater from the bay at an elevation of 0 to a reservoir at a desalination plant that has a water surface elevation of 255 feet. A 12-inch diameter DIP pipe (CHW = 120) which is 625 feet long connects the two bodies ..
A 3220-lb car enters an S-curve at A with a speed of 60 mi/hr with brakes applied to reduce the speed to 45 mi/hr at a uniform rate in a distance of 300 ft measured along the curve from A to B.
Investigators have determined that the rate equation for bacterial kill in batch chlorine contact chambers is: rxn rate = dC/dt=-kCt where C is the concentration of bacteria, k is the rate constant, and t is time.
Water at 20 degrees flows at a velocity of (V =) 2 m/s in a (D =) 250-mm diameter horizontal ductile iron pipe. Estimate the friction factor f in the pipe, and state whether the pipe is hydraulically smooth or rough.
Determine: a. the Level of Service for this segment; b. the loss in Level of Service, if due to construction the lane width is reduced to 10 feet and there are concrete barriers one foot away from either end of the pavement.
Establish a grass cover over a 10ha landfill. The root zone of the grass is 40cm deep. Increase the volumetric water content of root zone from 12% to 24%. How many cubic meters of water are needed?
Given computer-generated direction field. Then sketch, by hand, an approximate solution curve that passes through each of the indicated points. Use different colored pencils for each solution curve.
For a metal and wood structure, how would the economies of construction be obtained (pertaining to the mean and standard deviation of a probability of failure graph)?
A 32000 lb airplane lands on an aircraft carrier and is caught by an arresting cable. The cable is inextensible and is paid out at A and B from mechanisms located below deck and consisting of pistons moving in long oil-filled cylinders.
Fluids A and B ave specific gravities .75 and 1.00 respectively. If the mercury is used as manometer liquid determine the pressure difference between A and B
A 10-mm diameter bar of 1040 carbon steel is subjected to a tensile load of 50,000 N, taking it beyond its yield point. Calculate the elastic recovery (or strain) that would occur upon removal of the tensile load.
If it absorbs 100 Joules each cycle from the hot reservoir, how much work does it do. How much heat is given off in each cycle If each cycle takes 0.5 seconds, find the power output of the engine.
