Design a circuit with a 4-bit input representing the binary number A3A2A1A0. The output should be 1 if the input value is divisible by 3. Assume that the circuit is to be used only for the digits 0 through 9 (thus, values for 10 to 15 can be don't care conditions).
a. Draw the Karnaugh map and truth table for the function.
b. Determine the minimum expression for the function.
c. Draw the circuit, using only AND, OR, and NOT gates.
the overall volume compression ratio of a reversed carnot cycle working with air as a refrigerant is 10. the
The convection coefficient is determined. The following experimental arrangement uses the procedure to determine the convection coefficient for gas flow normal to a surface.
Design a ceiling diffuser. Air flows in the duct behind the diffuser and enters the diffuser at a pressure of 12.8psia, and a velocity of 200in/sec. The outlet of the diffuser is in the room, with atmospheric pressure of 14.5 psi. For the comfort of ..
a car air conditioning system operates with r-134a in the peak summer outside at 100degf and inside desired at 77degf.
a beam of rectangular cross section is 200 mm deep 100 mm wide and 3 m long. it is simply supported at each end. it has
A water brake is used to measure the power output of an engine, ?W . The water mass flow rate through the brake is m? = 7 kg s?1. Water temperatures at the brake inlet and outlet are T1 = 290K and T2 = 305K, respectively. The heat loss from the engin..
starting from rest the motorboat travels around the circular pathp 50m at a speed v0.8tms where t is in seconds.
Horsepower and efficiency of three-phase motor, If a fully loaded 440V, three-phase motor draws 12.4 A at 86% power factor (pf). It's speed is 1730 rpm and its torque output to a mechanical load is 29.1 lb-ft x 1.356 = 39.5 Nm.
an actual refrigerator absorbs 500 kj of heat from a sink at 250 k and reject 660 kj of heat to environment at 300 k.
a closed gas turbine unit uses neon as the working fluid. there are two stages of compression with intercooling from
a solar collector is made of a cover plate then a 5 cm air gap and then an absorber plate with insulation on the back
Nitrogen gas (N2) undergoes a process from p1 = 10 bar, T1 = 300 K to p2 = 12 bar, T2 = 1000 K. Assuming ideal gas behaviour, determine the change in specific entropy, in kJ/(kg K), assuming:
