Answer:
3.11 A
Explanation:
Use the given relations between power, horsepower, voltage, and current to find the current requirement for the motor.
P = hp(745.7 W) = (1/2)(745.7 W) = 372.85 W
I = P/V = (372.85 W)/(120 V) = 3.1071 A
The amperage required is about 3.11 A.
Answer:
Explanation:
The determination of any further properties requires the knowledge of two independent properties. (Temperature and specific volume in this case). The specific volumes for saturated liquid and vapor at 140 °C are, respectively:
Since , it is a liquid-vapor mixture. The quality of the mixture is:
The specific enthalpies for saturated liquid and vapor at 140 °C are, respectively:
The specific enthalpy is:
Answer: True
Explanation:Typical metals have a property of ductility and malleability that is metals can be drawn into wires or any other shape by beating or stretching the metal by putting the tensile strength or shear strength that pulls them apart . But while compression the metals are squeezed together which affects the hardness of a metal and they are not able to bear the compression force well and thus cannot show elastic-plastic behavior while compression .Therefore the statement given is true typical metals show elastic-plastic behavior in tension and shear but not in compression.
Explanation:
