What are the 3 standard views in an orthographic drawing? Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object. These views are known as front view, top view and end view. Other names for these views include plan, elevation and section. What are […]
Is a zero after a decimal significant?
Is a zero after a decimal significant? The number 0 has one significant figure. Therefore, any zeros after the decimal point are also significant. Example: 0.00 has three significant figures. Any numbers in scientific notation are considered significant. What is the rule for showing zeros to the right of the decimal point? Scientific notation, sometimes […]
How does a kangaroo move?
How does a kangaroo move? The kangaroo moves by hopping. They hop on their powerful hind legs and use their tails for balance and for steering. Even though kangaroos jump with their legs moving together, they are able to kick each leg separately when swimming. A Red Kangaroo can leap as far as 25 feet […]
What instrument measures the length of a cable?
What instrument measures the length of a cable? The cable length meter CableTool performs a precise measurement of the cable length by recording how long it takes an electric signal to cross through a cable and get back to the meter. How do you measure cable size? These methods only require minimal equipment and are […]
Which process in sheet metal is used for producing fluid tight joints?
Which process in sheet metal is used for producing fluid tight joints? To produce joints using the metal sheets ,we mainly use the welding method. And to produce,fluid tight joints we use a special type of joint,known as the seam welding. In this special type of welding the electricity is used instead of gas torch,to […]
What is the difference between a datum and a datum feature?
What is the difference between a datum and a datum feature? A datum feature is a part feature (or FOS), that contacts a datum during measurement. A datum is a theoretically exact plane (or axis or center-plane), from which dimensional measurement should be made. During measurement, the datum feature will contact the simulated datum which […]
What is hydraulic boundary layer?
What is hydraulic boundary layer? The fluid velocity varies from zero at the solid surface to the velocity of free stream flow at a certain distance away from the solid surface. This thin layer of changing velocity has been called the hydrodynamic boundary layer; a concept first suggested by Ludwig Prandtl in the year 1904. […]
How do you calculate resin ion exchange volume?
What is ug L in ppb?
How do you calculate rpm thrust?
How do you calculate rpm thrust? Given a rotational speed of 10,000 rpm, the calculation goes as follows: Power=0.015X103.2=24 W. The next step is to determine the thrust produced by a propeller. Equation 2 gives thrust based on the Momentum Theory. How do you calculate propeller RPM? The best way to determine the RPM of […]
