Why does a pressure cooker boil food more quickly than an ordinary pot? Food is cooked more quickly in a pressure cooker because at the higher pressure (1 bar/15 psi), the boiling point of water rises from 100 °C (212 °F) to 121 °C (250 °F). The hotter steam is able to transmit its thermal […]
How do you calculate the flow rate of a heat exchanger?
How do you know which vibrational modes are IR active?
How do you know which vibrational modes are IR active? In order to determine which modes are IR active, a simple check of the irreducible representation that corresponds to x,y and z and a cross check with the reducible representation Γvib is necessary. If they contain the same irreducible representation, the mode is IR active. […]
Which cutting variable affects tool life the most?
Which cutting variable affects tool life the most? Feed rate has the most significant effect on tool life followed by spindle speed and depth of cut. When the depth of cut is increased the specific cutting energy? As the cutting depth increases, groove geometry clearly reveals the ductile-to-brittle transition from the plastic deformation to a […]
What is the condition for critical damping?
What is the condition for critical damping? Critical damping is defined as the threshold between overdamping and underdamping. In the case of critical damping, the oscillator returns to the equilibrium position as quickly as possible, without oscillating, and passes it once at most [1]. Why is critical damping important? Critical Damping is important so as […]
What is the git command for staging all the changes you have in your local repository?
What is the git command for staging all the changes you have in your local repository? The git command git commit takes all changes in the Staging Area, wraps them together and puts them in your Local Repository. What does the git command do? Git is a type of version control system (VCS) that makes […]

What is the role of a dissertation chair? The dissertation committee chair, working with department administrative staff, helps steer the student through the intellectual stages and institutional […]
What is the most important factor to consider when selecting cutting speed for engine lathe operations?
What is the most important factor to consider when selecting cutting speed for engine lathe operations? The primary factor in choosing feed and speed is the material to be cut. However, one should also consider material of the tool, rigidity of the workpiece, size and condition of the lathe, and depth of cut. What are […]
What is a 20W CFL equivalent to?
What is the function of a smoothing capacitor?
What is the function of a smoothing capacitor? A Smoothing Capacitor is used to generate ripple free DC. Smoothing capacitor is also called Filter capacitor and its function is to convert half wave / full wave output of the rectifier into smooth DC. What is smoothing in rectification? Smoothing is performed by a large value […]
