Consider the following statements with reference to Jet stream. 1. The Jet Stream is a geostrophic wind. 2. There are two permanent jet streams – subtropical jets at mid-latitudes and polar front jets at lower latitudes. 3. Temperature also influences the velocity of the jet stream. The lower the difference in air temperature, the faster the jet stream. Which of the statements given above is/are NOT correct?
The maximum number of jets, generally, employed in an impulse turbine without jet interference are
The maximum number of jets generally employed in impulse turbine without jet interference is
The maximum number of jets, generally, employed in an impulse turbine without jet interference are __________
Which of the following statement(s) is/are incorrect? (i) A turbine is called an impulse turbine if at the inlet of the turbine total energy is only kinetic energy (ii) A turbine is called a reaction turbine if at the inlet of the turbine the total energy is kinetic energy and pressure energy (iii) The inward flow reaction turbine having radial discharge at the outlet is known as Kaplan turbine
Consider the following statements in connection with hydraulic turbines: 1. The Kaplan turbine is a radial flow turbine in which the guide vane angles as well as the runner vane angles are adjustable. 2. Francis and Kaplan turbines are provided with draft tubes which carry water from exit of runner to tail water to increase the gross head across the turbine. 3. The parts of turbines susceptible to cavitation are the guide vanes and runner vanes – drastically reducing the turbine efficiency. 4. The specific speed of a 4-jet Pelton turbine will be 28 if the specific speed of a single-jet Pelton turbine is 14. Which of the above statements are correct?
The important characteristics about Jet stream are- Jet streams are narrow, fast-flowing, meandering air currents in the atmospheres of some planets, including Earth. The strongest jet streams are subtropical jets at the higher altitude and somewhat weaker are polar jets.
In the question given below, there are three statements followed by three conclusions. Taking the given statements to be true even if they seem to be at variance with commonly known facts, read all the conclusions and then decide which of the given conclusions logically follows the given statements. Statements: 1. Some Buildings are Car 2. No Car is Jet 3. All Jets are Tablets Conclusions: I. Some Jets are Buildings II. Some Tablets are Jets III. No Building is Tablet
