What is the principle of sewage treatment? The basic principle of the working of a biological treatment plant is decomposition of the raw sewage. This process is done by aerating the sewage chamber with fresh air. The aerobic bacteria survive on this fresh air and decompose the raw sewage which can be disposed of in […]
What supports a white dwarf star against gravitational collapse?
What supports a white dwarf star against gravitational collapse? In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy. What keeps white dwarfs and neutron stars from collapsing? The fact that […]
Can you use a carpet cleaner as a regular vacuum?
Can you use a carpet cleaner as a regular vacuum? “Carpet cleaners are nothing like a standard upright vacuum,” says Larry Ciufo, who oversees Consumer Reports’ carpet cleaner tests. In fact, “the instructions for these machines tell you to vacuum your floor first using a conventional vacuum cleaner, and then use the carpet cleaner to […]
What are the five basic families of shape production processes?
What are the five basic families of shape production processes? The four basic families of shape production processes are: (1) Casting, (2) Material removal, (3) Deformation processes, and (4) Consolidation processes. Casting processes can produce extremely complex shapes, but may have defects related to shrinkage and porosity. What are the advantages of casting process? Advantages […]
How is potential energy transformed into kinetic energy on a roller coaster?
How is potential energy transformed into kinetic energy on a roller coaster? When the marble is released, its potential energy transforms into the energy of motion or mechanical kinetic energy. As a coaster car glides over the hills and through the loops of the roller coaster, energy converts back and forth between kinetic energy and […]
What is the importance of budgeting within an organization?
What is the importance of budgeting within an organization? It enables the business owner to concentrate on cash flow, reducing costs, improving profits and increasing returns on investment. Budgeting is the basis for all business success. It helps with both planning and control of the finances of the business. What is a budget How does […]
How can a flying Aeroplane be in dynamic equilibrium?
How can a flying Aeroplane be in dynamic equilibrium? Spacecraft flight dynamics involve three main forces: propulsive (rocket engine), gravitational, and atmospheric resistance. Propulsive force and atmospheric resistance have significantly less influence over a given spacecraft compared to gravitational forces. What are the 3 axis of rotation in an aircraft? Regardless of the type of […]
Can you get in trouble for uploading to Course Hero?
Can you get in trouble for uploading to Course Hero? Looking at Course Hero notes to get ideas from past students about what they understood from the course and their study/revision notes etc is not misconduct. Uploading your own study notes you have from a course is not misconduct. Is using Course Hero illegal? The […]
How do you figure volume of a cylinder?
How do you calculate pressure in a manometer?
How do you calculate pressure in a manometer? Manometers. One of the most important classes of pressure gauges applies the property that pressure due to the weight of a fluid of constant density is given by p = hρg. What is the formula for calculating atmospheric pressure? Atmospheric pressure is the pressure caused by the […]
