The answer is ""
Explanation:
Air flowing into the
Flow rate of the mass
inlet temperature
Pipeline
Its air is modelled as an ideal gas Apply the ideum gas rule to the air to calcule the basic volume v:
For a short time a rocket travels up and to the left at a constant speed of v = 650 m/s along the parabolic path y=600−35x2m, wh
ere x isin m. The origin of polar coordinate system is the same as the origin of the rectangular coordinate system xy.
Part A
Determine the radial component of velocity of the rocket at the instant when its transverse coordinate θ = 60∘, where θ is measured counterclockwise from the x axis.
Express your answer to three significant figures and include the appropriate units.
Part B
Determine the transverse component of velocity of the rocket at the instant when its transverse coordinate θ = 60∘, where θ is measured counterclockwise from the x axis.
Express your answer to three significant figures and include the appropriate units.

Solution :
Given :
External diameter of the hemispherical shell, D = 500 mm
Thickness, t = 20 mm
Internal diameter, d = D - 2t
= 500 - 2(20)
= 460 mm
So, internal radius, r = 230 mm
= 0.23 m
Density of molten metal, ρ =
=
The height of pouring cavity above parting surface is h = 300 mm
= 0.3 m
So, the metallostatic thrust on the upper mold at the end of casting is :
Area, A
= 7043.42 N
