A three-phase 5 hp, 208 V motor has an efficiency of 92%, and a power factor of 0.87 (lagging) when it runs at full power. Calculate the motor phase currents and line currents if the motor is wye connected, and delta connected.
a cost to produce, P, of $4.00. If we were able to reduce this to $3.55 through greater attention in the design, and if the cost to improve the design (in NRE) is $35,000, how many units must we sell to recover the increased design cost.
A 2.4KV, single-phase circuit suppllies a load of 250KW at a lagging power factor, and the load current is 160A. If it is necessary to improve the power factor, determine the following: (a)The uncorrected poer factor and reactive load.
define a one-dimensional potential well having energies U as a function of position x as follows: U=infinity for x= -1nm to x=0; U=0 eV for x=0 to x=5nm; U=10 eV for x=5nm to x=7nm; U=0 for x>7nm and x
pecify the value for R. What is the diode current with the load connected What is the increase resulting in the output votage when the load is disconnected What change results if the load resistance is reduced to 100ohms? To 75ohms To 50ohms
Write a ladder logic program needed to implement each of the following (assume inputs A, B and C are all normally open toggle switches).
Then find the total energy stored in the battery before it is connected to the bulb. Determine the total amount of charge that has pessed through the wires that connect the battery and the bulb.
An amplifier output is being evaluated by a technician. The output is found to be a sine wave. The measured time lapse from one sine-wave peak to the next is 5 milliseconds.
The messages being sent are 2 milliseconds long. Computer A starts sending a message on the bus; 250 microseconds later, Computer B starts to send a message, and 250 microseconds after that, Computer C starts to send a message.
What is the resolution of an ADC with a word length of 12-bits and an analogue signal input range of 100 V A sensor produces a maximum analogue output of 5V. What word length is required for an ADC if there is to be a resolution of 10mV
Suppose it is known that a 5MHz transducer axis makes an angle of 30 degrees relative to the direction of motion of blood in a vessel. If the Doppler frequency is measured to be +500Hz, what is the velocity of the blood
A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving.
Calculate the standard enthalpy change for the reaction of an aqueous solution of barium hydroxide, Ba(OH)2, with an aqueous solution of ammonium nitrate, NH4NO3, at 25°C. The complete ionic equation is
