Answer:
final pressure = 0.7 MPa
quality = 20 degree super heat.
Explanation:
Given data:
water temperature 120 degree celcius
quality
we know that from saturated water temperature table . for T =120 DEGREE
we know that
= 0.001060 + 0.33(0.89133- 0.001060)
= 0.29485 m^3/kg
frinal temperature of water is
= 120 + 65 = 185 Degree
from saturated water temp. table
for T = 185 degree, VG = 0.17390 m^3/kg
from super heated table by interpolation
final pressure = 0.7 MPa
quality = 20 degree super heat.
Answer:
Inside the Sun.
Explanation:
Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium. This fusion process occurs inside the core of the Sun, and the transformation results in a release of energy that keeps the sun hot.
Answer:
3180.86 Nm
Explanation:
Moment of inertia for shaft AB,
Torque in solid shaft AB will be given by
Where is shear stress, is polar moment of inertia for shaft AB, r is the radius of shaft B
The inner diameter of pipe CD can found considering that the thickness of pipe is 0.006 m hence diameter= 0.09-(2*0.006)= 0.078 m
Moment of inertia for shaft CD will be
Torque for shaft CD will be
and here r = 0.045 m
The minimum of the two torques is the largest torque that can be applied. Therefore, the torque to apply equals 3180.86 Nm
Answer:
The mass of the air is 0.0243 kg.
Explanation:
Step1
Given:
Stroke of the cylinder is 320 mm.
Bore of the cylinder is 280 mm.
Pressure of the air is 101.3 kpa.
Temperature of the air is 13°C.
Step2
Calculation:
Stroke volume of the cylinder is calculated as follows:
V = 0.0197 m³.
Step3
Assume air an ideal gas with gas constant 287 j/kgK. Then apply ideal gas equation for mass of the air as follows:
PV=mRT
m= 0.0243 kg.
Thus, the mass of the air is 0.0243 kg.
Answer:
Unique Selling Proposition
Explanation:
Unique Selling Proposition (USP) is the distinguishing feature that makes one product or business better than its competitor in the market. Jen has developed a competitive advantage of the new sunglasses brand making the company to sell their products. This is an example of USP.
