Answer:
a) 180 m³/s
b) 213.4 kg/s
Explanation:
= 1 m²
= 100 kPa
= 180 m/s
Flow rate
Volumetric flow rate = 180 m³/s
Mass flow rate
Mass flow rate = 213.4 kg/s

Answer:
10 ft or 3.048 m (for unqualified person)
1.09 ft or 0.33 m (for qualified person)
Explanation:
OSHA has prescribed "Minimum Approach Distance - MAD" to ensure safety of personnel working with electrical power lines.
For a unqualified person:
The minimum approach distance is 10 ft or 3.048 m
For a qualified person:
For a voltage in the range of 300V to 750V (Phase to Ground or Phase to Phase) the minimum approach distance is 1.09 ft or 0.33 m
Since 600V lies in the above range hence it is applicable on 600V.
OSHA has developed a full list of minimum approach distance according to the level of voltages (50V to 72000V)
Answer:
The world wars. Most notably world War II
Explanation:
The demand for aircrafts during these events led to extensive research into the design of aircrafts. Aircraft advanced within these years from a simple design to a more complex design; capable of carrying fire power and even became bomb equipped. Also, the material of choice of production moved from wood to metal and the engine was improved on to gain more speed and maneuverability.
