What is the setting of October sky?
October Sky is based on the lives of four young men who grew up in Coalwood, West Virginia. Principal photography took place in rural East Tennessee, including Oliver Springs, Harriman and Kingston in Morgan and Roane counties.

Who is Mr bykovski in October Sky?
In “October Sky,” Ike Bykovski, a character who was a composite of real miners Hickam knew, died in a mine accident after helping Homer with his rockets. In the film, Homer said he thought his father sent Mr
Who is Dorothy Plunk?
Dorothy Plunk is, in addition to being beautiful, an intelligent student—ultimately the valedictorian of Big Creek. Although Dorothy frequently expresses her affection for Homer, she never agrees to date him—she’s usually too busy dating other, more “serious” people—including, much to Homer’s chagrin, Jim Hickam.
What happened to Miss Riley in October Sky?
Riley, the teacher who inspired the Rocket Boys and is depicted in the film October Sky. Miss Riley died of Hodgkin’s disease at the age of 31.
What started the fire in October Sky?
In October, news of the Soviet Union’s rocket launch of Sputnik 1 reaches Coalwood. The next day, they are arrested accused of having started a forest fire with a rocket that had gone astray. After John picks up Homer from the police station, Roy Lee is seen getting beat up by his stepfather, Vernon.
Who is Mr Turner in October Sky?
Chris Ellis
Why did Homer’s father want him to work in the mine?
As Homer’s sympathetic mother Elsie explains to Homer, the boy’s father loves the mine more, perhaps, than his own family. He expects Homer to work in the mine because that is the only reality he has ever known.
Why is the nozzle so important in October Sky?
Why is the “Nozzle” important? Directs the flow of the hot gases.
What is the most significant thing Homer Hickam does in October Sky?
The most significant thing Homer does is to pursue and continue the vision that exists in his mind, and in the subjective experiences of the Rocket Boys. The idea that the boys are able to pursue their dreams in a setting that is not immediately appreciative of their elements is vitally important.
How fast is Sputnik and how long is its orbit?
Sputnik 1 was launched during the International Geophysical Year from Site No.1/5, at the 5th Tyuratam range, in Kazakh SSR (now known as the Baikonur Cosmodrome). The satellite travelled at about 29,000 kilometres per hour (18,000 mph; 8,100 m/s), taking 96.2 minutes to complete each orbit.
What is the purpose of the nozzle at the end of the rocket?
A rocket engine uses a nozzle to accelerate hot exhaust to produce thrust as described by Newton’s third law of motion. The amount of thrust produced by the engine depends on the mass flow rate through the engine, the exit velocity of the flow, and the pressure at the exit of the engine.
Where did Homer go to show the results of all his hard work?
Where did Homer go to show the results for all his hard work? He goes to the national science fair in Indiana.
Why does rocket thrust increase with altitude?
At full throttle, the net thrust of a rocket motor improves slightly with increasing altitude, because as atmospheric pressure decreases with altitude, the pressure thrust term increases. Since ambient pressure changes with altitude, most rocket engines spend very little time operating at peak efficiency.
Which nozzle is used in rocket engine?
A rocket engine nozzle is a propelling nozzle (usually of the de Laval type) used in a rocket engine to expand and accelerate the combustion gases produced by burning propellants so that the exhaust gases exit the nozzle at hypersonic velocities.
What does a nozzle do Sanfoundry?
Nozzle is used to control direction or characteristics of flow. Explanation: Nozzle is used to control the direction and characteristics of flow. Explanation: Nozzles are used to control the rate, speed, direction of flow. Explanation: A nozzle used to send the fluid in coherent stream is called as jet.
What is nozzle ratio?
[′näz·əl ik′pan·shən ‚rā·shō] (design engineering) Ratio of the cross-sectional area for gas flow at the exit of a nozzle to the cross-sectional area available for gas flow at the throat.
What is another name for the nozzle area ratio?
For evaluating delivered performance parameter values, static tests or flight test of full-scale models are used. 2. What is another name for the nozzle area ratio? Explanation: Nozzle area ratio is defined as Ae/A*, where Ae denotes exit area and A* denotes throat area.
How does nozzle size affect velocity?
The larger nozzle diameter gives more mass of fluid to be carried. It is also related to the momentum energy generated that when the fluid velocity s constant with increasing fluid mass so the momentum gets larger then the jt plunges deeper. The depth of bubble penetration also increased with increasing jet velocity.
What is another name of converging nozzle?
This nozzle configuration is called a convergent-divergent, or CD, nozzle.
What is a flow nozzle?
: a tapered length of tube that causes a fall of pressure head in a liquid flowing through it from which the rate can be calculated.
How do you calculate flow rate of a nozzle?
3 Flow rate
- Any nozzle will produce certain flow rate at a given pressure differential.
- The flow rate for a given nozzle can be calculate by the following formula.
- Q= Flow rate.
- K = K factor for nozzle.
- P = Pressure differential at the nozzle.
- n = Is a constant that depends upon the spray pattern type.
How does a flow nozzle work?
When a flow nozzle is placed in a pipe carrying whose rate of flow is to be measured, the flow nozzle causes a pressure drop which varies with the flow rate. This pressure drop is measured using a differential pressure sensor and when calibrated this pressure becomes a measure of flow rate.
Does a nozzle increase pressure?
In a convergent nozzle, there is an increase in velocity and a decrease in pressure, but we know that pressure is inversely proportional to area. To maintain a constant amount of fluid moving through the restricted portion of the nozzle, the fluid must move faster
Can a nozzle reduce pressure?
The pressure drops in a nozzle is because of the Bernoulli Principle . As fluid enters the smaller cross-section, it has to speed up due to the conservation of mass. Thus pressure energy is converted into faster forward motion, known as velocity. This change makes the pressure drop.
What happens to pressure if area increases?
Answer. As pressure and area are indirectly proportional to each other . so , if area increases , pressure decreases
How do you calculate nozzle pressure?
Calculates the needed diameter of a nozzle for a specific pressure and flow rate.
- Pressure: psi. ft of water. m of water. bars. kPa. atm. in of Mercury.
- Flow Rate: gpm. lps. cfs. lpm.
- Diameter: in. 128ths in. 64ths in. 32nds in. 16ths in. 8ths in. mm. cm.
What is the GPM formula?
For the best accuracy measure the flow 3 or 4 times and average the times together. The formula to find GPM is 60 divided by the seconds it takes to fill a one-gallon container (60 / seconds = GPM). Example: The one-gallon container fills in 5 seconds, breakdown: 60 divided by 5 equals 12 gallons per minute.
