An ordinary egg can be approximated as a 5.5-cmdiameter sphere. The egg is initially at a uniform temperature of 8°C and is dropped into boiling water at 97°C. Taking the properties of the egg to be p=1020 kg/m3 and cp 3.32 kJ/kg · °C, determine how much heat is transferred to the egg by the time the average temperature of the egg rises to 80°C.
1. The third unit of an aircraft hangar project was completed in 2700 hours. The fifteenth unit was built in 2100 hours. What is the learning rate (based on doubled units)? How long would it take to build the hundredth unit?
Refrigerant 134a is compressed at steady state from 2.4 bar, 0 degrees celcius, to 12 bar, 50 degrees celcius. Refrigerant enters the compressor with a volumetric flow rate of 0.38m^3/min, and the power input to the compressor is 2.6 kW.
According to Archimede's principle, the buoyancy force actingon that object that is partially immersed in a fluid is equal tothe weight that is displaced by the portion of the object that issubmerged.
Which measurement contributes to large amount of error? how would you improve on these measurements if you repeated this lab exercise?
Are either of the Ax or Jx forces relevant to finding the tension between H and J? If so, what is the easiest way to solve for those 2 unknowns?
A force, 90 N in magnitude, is applied to control rod AB as shown. Knowing that the length of the rod is 225 mm, determine the moment of the force about point B by resolving the force into components along AB and in a direction perpendicular to AB..
the 30 ft simple beam shown has lateral support spacing at 15 ft for its compression flange and consists of 50 ksi steel. the beam supports a gravity service dead load of 1.2 klf (includes beam weight) and a gravity live load of 3.4 klf
A pitot-static tube is used to measure the velocity at the center of the pipe. If the fluid velocity is 10 ft/s, what is the deflection on a mercury manometer connected to the pitot-static tube
this concentration is based on an assumption that the individual is generally healthy and is exposed for 8 hours per day over a working lifetime ( that is from age 18 to 65 years). assuming a body weight of 78 kg and an inhalation rate of 0.63 m^3..
The average rate of water consumption from this tank is 6.25 kL per day, every day. The farmer refills the tank (overnight) every 14 days, using a pump that takes water from a nearby river. The top of the tank is 53m (vertically) above the level o..
How much must he set aside in his savings to account for the 3-months summer to cover his rent for next year. The savings account earns 3% with monthly compounding.
What is the shear rate in the water between a sliding and standing plate, if V = 10 ft/s is the moving plate velocity and 0.1 in. is the distance between the plates
