- 5 apparatus or devices used for Flash, Fire, and Pour Points of lubricants and fuelsA power nozzle throws a jet of water which is 30 mm in diameter at a velocity of 40 m/s. What is the power exerted by the nozzle? Select one: O a. 80 hp O b. 30 hp O c. 20 hp O d. 50 hpSelect the correct statement. O a. The source of solar power is from sunlight and it is captured by wind mills and converted into electricity. It is also used for heating, drying etc O b. Wind mills can have a capacity to produce energy in a large-scale, which is an alternative to fossil fuels. O c. Most of the renewable energy sources are available finite in nature, so it will run out easily as like as non renewable energY sources. O d. Construction cost of dam is very less and also it can cause flooding of surrounding communities and landscapes.
- An impulse turbine operating with a single nozzle has a specific speed of 5. What will be the approximate specific speed of the turbine if the turbine is operated with one more additional nozzle of the same size?Question 4 of 10 0/1 E View Policies Show Attempt History Current Attempt in Progress In a diesel engine the fuel is ignited when it is injected into hot compressed air, heated by the compression itself. In a typical high-speed diesel engine, the chamber in the cylinder has a diameter of 10.7 cm and a length of 13.4 cm. On compression, the length of the chamber is shortened by 12.7 cm (a “5-inch stroke"). The compression of the air changes its pressure from 1.00 to 39.5 atm. The temperature of the air before compression is 391 K. As a result of the compression, what will be the final air temperature (in Kand °C) just before the fuel injection? temperature = K = i °C eTextbook and Media Hint Assistance Used Determine the volume change as a way to get a handle on the new temperature. What equation relates pressure, temperature, and volume? The volume of the cylinder = z r² (height). Remember that the radius is half the diameter. Save for LaterDetermine dimensions and materials for a flywheel that should be able to store energy. - The flywheel must store 30 MJ at a rotation speed of 5,000 rpm - The flywheel consists of a hub, a thin disc, and a solid ring. - The dimensions you have to decide are d1, d2, t and B - The design is shown in the sketch below which shows the wheel in cross section
