Answer:
Weight of oil will be 8.1 N
So option (b) is correct
Explanation:
We have given specific gravity of oil = 0.83
We know that specific gravity is given by
So
Density of oil
Volume is given as 1 liter =
We know that mass
Weight of oil is given by
So option (b) is correct
Answer:
C. Primary auxiliary view
Explanation:
A secondary auxiliary view is obtained by projecting the primary auxiliary view to the plane which lies perpendicular to the true (complete) edge length of the primary auxiliary view. In the secondary auxiliary view, the sides that come after the closer edges of the primary auxiliary view becomes visible making it appear that the side after the closer edge is the visible top of the view
Therefore, the drawing necessary for him to create the secondary auxiliary view is the <em>primary auxiliary view.</em>
Answer:
Q = 8.845 DEGREE
Explanation:
given data:
combine Mass for 6 cylinder (M) =15 Kg/hr
mass of each cylinder (m) = 15/6 = 2.5 Kg/hr = 0.000694 Kg/ sec
Engine speed (N)= 1500rpm
Diameter of one nozzle hole ( d) = 200 micrometer = 0.0002 m
Discharge Coefficient (Cd) = 0.75
Pressure difference = 100 MPa
Density of fuel = 800 kg/m^3
velocity of fuel is
injected fuel volume (V) =Area of given Orifices × Fuel velocity × time of single injection × no of injection/sec
we know that p = m/ V
So
putting these value in volume equation and solve for Discharge
Q = 8.845 DEGREE
Answer: True
Explanation: It is correct that during a cycle the energy of the system remains unchanged. Total energy consist of the initial energy and the final energy in a system and both remain equal in a system whether they are in cycle or not ans also according to the law of conservation of energy ,total energy cannot be destroyed or created. Thus the while a cycle goes on energy will remain the same.
Answer:
Option D
Material has uniform properties throughout.
Explanation:
A homogeneous material is a material that exhibits uniform properties throughout and these properties cannot be separated. These materials can be metals, ceramics or alloys that exhibit similar properties throughout. The similar properties may include evaporation point, density and other properties.
