An air compressor delivers 820 cfm of free air. Compute the flow rate of air in a pipe in which the pressure is 80 psig and the temperature is 75°F.
The heat transfer coefficient inside the pipe is 1600 W/m2K. Plot the liquid temperature as a function of position in the pipe.
drag measurements were taken for a sphere with a diameter of 5 cm moving at 4ms in water at 20 degrees celsius. the
R-134a enters the condenser of a refrigerator at 800kPa and 50oC at a rate of 0.018kg/s and leaves at 800kPa as a saturated liquid. It is known that the compressor consumes 1.2kW of electricity at this operating condition. Determine 1) heat rejection..
consider a rankine cycle with a single regenerative feed-water heater. the steam enters the turbine at 30 bar 400c and
Determine both the resultant normal force and the resultant frictional force that all the wheels of the car exert on the road at this instant. Neglect the size of the car.
a 12-kg solid whose specific heat is 2.8 kjkg degree c is at a uniform temperature of -10 degree c. for an environment
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..
a waste treatment pond is 50 m long and 15 m wide and has an average depth of 2 m. the density of the waste is 85.3 lb
suppose that the minimum and maximum ages for typical textbooks currently used in college courses are 2 and 8 years.
Find the natural frequencies of the cantilever beam carrying an end mass M shown in Fig. 12.34, using a one-beam element idealization.
a 3000lb car is traveling at 60mih up an inclined surface of 5deg when the brakes are applied creating a constant
where A and B are constants. (b) A critically damped oscillator is at rest at equilibrium. At t = 0 it is given a blow of total impulse I. Sketch the motion, and find the time at which the velocity starts to decrease.
