A steel tape is used to measure a distance of 20 m at a 10 0C. Assuming that the tape will measure the true distance when the temperature is 20 0C. What would be the indicated distance at 10 0C? What would be the indicated distance at 400C?
A vertical run of copper tubing, 5 mm in diameter and 20 cm long, carries condensation vapor at 60 °C through 27°C air. What is the total heat loss?
It is necessary to design a square-section composite bar that will withstand an applied load without deflecting more than a specified amount.The design specification for the bar, including its dimensions and loading criteria, is given below.
A gasoline engine is modeled as an Otto cycle. It has at temperature and pressure at the beginning of compression of 10°C and 90 kPa. The compression ratio is 7 and the specific energy added to the air during the heat addition process is 1432.46 ..
A paper clip is made of wire 0.7 mm in diameter. If the original material from which the wire is made is a rod 25 mm in diameter, calculate the longitudinal engineering strain and true strain that the wire has undergone during processing.
Knowing that the modulus of elasticity of brass is 105 GPa, determine the magnitude of the load P for which the deflection of the plug is 1,25 mm downward.
An 8-kg plunger is released from rest in the position shown and is stopped by two nested springs; the constant of the outer spring is k1 = 4 kN/m and the constant of the inner spring is k2 = 12 kN/m. If the plunger is released from the height
Find the slope of the liquid surface in the can if the merry-go-round spins at 0.3 revolution per second.
The mean diameter of a conical friction clutch is 250mm with a width of the conical surface being 50mm. The clutch is lined with a material having a coefficient of friction of 0.25
Evaluate the maximum theoretical power that can be developed by the turbine, in kW, and the corresponding exit temperature.
For the preliminary design a power of 0.5kW/m^3 volume is to be used. Calculate the dimensions of the agitation system, rpm, and kW power.
