1. For a satellite cruising in a circular orbit at an altitude of 500 km, determine the period of revolution, the flight speed, and the energy expended to bring a unit mass into this orbit.
2. A large ballistic rocket vehicle has the following characteristics: propellant mass flow rate: 12 slugs/sec (1 slug = 32.2 lbm = 14.6 kg); nozzle exit velocity: 7100 ft/sec; nozzle exit pressure: 5 psia (assume no separation); atmospheric pressure: 14.7 psia (sea level); takeoff weight: 12.0 tons (1ton = 2000 lbf); burning time: 50 sec; nozzle exit area: 400 in. 2 Determine
(a) the sea-level thrust;
(b) the sea-level effective exhaust velocity;
(c) the initial thrust-to-weight ratio;
(d) the initial acceleration;
(e) the mass inverse ratio m0/mf .
Design a sieve plate column to perform this separation, for a feed rate of 10,000 kg/hour. Treat the feed as a binary mixture of ethanol and water. Take the feed temperature as 20 °C. The column will operate at 1 atmosphere.
A mixture contains only NaCl and Fe(NO3)3. A 0.456-g sample of the mixture is dissolved in water, and an excess of NaOH is added, producing a precipitate of Fe(OH)3.
Product X takes 1 machine hour per unit and Product Y takes 5 machine hours per unit. Which of the following is one of the constraints for this linear program?
Determine the longest wavelength (in cm) of X-rays that is still capable of producing diffraction in copper, Cu.
Compute graphically the flowrate and the pump head at the operation conditions - Repeat the question for the case of two identical pumps in series
Show sample calculations (including all steps for finding ρ, γ, and SG starting fmm raw data) for ONE or the fluids or objects measured during this laboratory.
Describe a procurement task. Rate it for the amount of uncertainty of the scope, cost, schedule, and risk. Choose a contract type and explain why that contract type would be an appropriate choice for that set of uncertainties.
When the supply frequency is increased to 90 Hz, while keeping the flux density constant, the total core loss is found to be 3000 W. Determine the hysteresis and eddy-current losses separately at both frequencies.
In order to make it into a common base amplifier, terminals a and b are connected together, and capacitor CE is disconnected from ground and used to couple a signal from a source to the emitter. Determine Ri, Rin, Av1, and Ai.
What is the minimum value of qo so that the bottom fibers just begin to yield? What are the depths of plastic penetration d1 and d2 for a load qo that is 1.1 times the value just calculated.
Calculate the efficiency of the induction generator.
The bulbs, which arestirred and of equal volume, initially contain binary gas mixtures of different compositions.At time zero, the valve is opened; at time t, the valve is closed, and the bulkcontents are analyzed. Explain how this information can..
