1. Determine the total availability of a 7.00 × 10-3 kg incompressible lead bullet traveling vertically at 1000. m/s at a height of 50 m above the ground. The temperature of the bullet is 150.°C and its specific heat is 0.167 kJ/kg ·K. The local environment is at 0.101 MPa and 20.0°C.
2. A stationary tethered balloon contains helium gas (an ideal gas here) at 0.00°C and 0.0700 MPa at a height of 1000. m. Determine the specific availability of the helium in the balloon relative to the ground, where the local environment is at p0 = 0.101 MPa and T0 = 20.0°C.
Capacitors c1= 8.50μF andc2=3.50μF are charged as a parallel combination across a 36-V battery. Calculate the initial voltage across, and initial chargeon each capacitor. a) Calculate the resulting charge on each capacitor
a single phase 440V 80kW load with a lagging Pf of .8 is supplied through a feeder of .6+j1.6 ohms and a single phase 100 kVA, 220/440 V transformer. the equiv impedance of the transformer referred to the High Voltage side is 1.15+j4.5 ohm.
A single phase full-wave half-controlled bridge converter feeds an inductive load. The two SCRs in the converter are connected to a common DC bus. The converter has to have a free-wheeling diode-
Write an assembly-language program to add $40 to each element of list1 and store it to the corresponding element of list2. Use a loop. ORG $2000 LIST1 DC.W $21, $442, 3, 4, 5
An amplifier with a power gain of 26 dB, is using a dual power supply of +/- 14 V. Find the peak-to-peak value of the largest input signal the amplifier can process without clipping.
A 60-Hz, 220-V-rms source supplies power to a load consisting of a resistance in series with a capacitance. The real power is 2000W, and the apparent power is 2500VA. Determine the value of the resistance and the value of the capacitance.
Suppose that the power system is operating under typical daytime loads, and the transmission line between Bus 4 and Bus 5 open circuits. What happens to the voltages on each bus now? Are any of the transmission lines overloaded?
In Chapter 3, we showed how to perform multiplication of unsigned integers by addition of partial products. Construct a multiplier for two 16-bit operands containing just one adder that adds successive partial products over successive clock cycles..
Who was introduced the right hand rule for determining the direction of the induced EMF? -- Where is rule is used?
How can an Si shaped pulse response be trimmed by means of a schematic circuit.
When the input returns 1the sequence stops were it was left off. The output should change only on a rising clock edge. Make 000 the initial state. Assume an implicit rising clock is ANDed with every FSM transition condition.
