Answer:
47.10 m/s
Explanation:
Diameter of the horizontal pipe, d = 7 cm = 0.07 m
Area of the horizontal pipe, A =
or
A = = 0.00384 m²
Head between the water surface and the pipe level, z = 4 m
Head added by the pump, hp = 8 - 200Q²
where, Q is the discharge
losses, hL = 5 m
now,
applying the Bernoulli's theorem between the water surface and the pipe outlet,
we have
where,
P₁ = pressure at the water surface = 0 (as atmospheric pressure only)
V₁ = Velocity at the free surface = 0
ρ is the density of the water
P₂ = pressure at the outlet = 0 (as atmospheric pressure only)
V₂ = Velocity at the outlet
on substituting the values, we get
or
or
also,
Q = A × V₂
thus,
or
V₂ = 47.10 m/s
Answer: they are connected in series.

Answer:
The specific volume of the super heated steam is 0.2139 m³/kg.
Explanation:
Super heated steam is the condition where only compressed vapor of water present. This is not containing any liquid form of water. Super heated steam has very high pressure depending upon temperature. If heat supplied increases after saturation vapor condition of the water, the water fuses into steam completely. Properties of super heated steam are taken from the super heated steam table.
Given:
Temperature of superheated steam is 300°C.
Pressure of the super heated steam is 1.2 Mpa.
Calculation:
Step1
Value of specific volume of the super heated steam is taken from superheated steam table at 300°C and 1.2 Mpa as follows:
Specific volume is 0.2139 m³/kg.
Step2
All other properties are also taken from the table as:
Internal energy is 2789.7 kj/kg.
Enthalpy is 3046.3 kj/kg.
Entropy is 7.034 kj/kgK.
The part of table at the temperature 300°C and pressure 1.2 Mpa is shown below:
Thus, the specific volume of the super heated steam is 0.2139 m³/kg.

Answer:
A. National Highway Safety Act
Explanation:
The National Highway Safety Act establishes general guidelines concerning licensing, vehicle registration and inspection, and traffic laws for state regulations. The act was made in 1966 to reduce the amount of death on the highway as a result of increase in deaths by 30% between 1960 and 1965
National Traffic and Motor Vehicle Safety Act regulates vehicle manufacturers by ensuring national safety standards and issuance recalls for defective vehicles
Uniform Traffic Control Devices Act defines shapes, colors and locations for road signs, traffic signals, and road markings
