How do you finish PLA prints? The technique to polish your prints is simple. Get a soft cotton cloth, and apply a small amount of liquid polish. Then apply to your 3D print surface in small circles until all the polish is rubbed into the surface. Once you’ve finished that, the surface should look reasonably […]
What does 95 percent compaction mean?
What does 95 percent compaction mean? 95% compaction means that the soil on the construction site has been compacted to 95% of the maximum density achieved in the lab. How do you calculate soil compaction percentage? 3.7 Calculate percent relative compaction by dividing the dry density of the material from the test site by that […]
What did the space probe Rosetta do?
What did the space probe Rosetta do? Rosetta was the first spacecraft to fly close to Jupiter’s orbit using solar cells as its main power source. Rosetta was the first spacecraft to orbit a comet nucleus, and was the first spacecraft to fly alongside a comet as it headed towards the inner Solar System. What […]
Which is stronger LDPE or HDPE?
Which is stronger LDPE or HDPE? LDPE is softer, more flexible and melts at a lower temperature than HDPE. LDPE is used in sandwich bags and other types of packaging. HDPE is harder, has a higher chemical resistance and can withstand higher temperatures. What is the difference between HDPE Lldpe and LDPE? This gives LLDPE […]
How do you calculate pump discharge pipe size?
How do you calculate pump discharge pipe size? He said his rule of thumb was to size the discharge pipe to that of the pump’s discharge flange. For example, if the pump’s discharge nozzle was 150mm, he would use a 150mm nominal size pipe for his discharge header. What is pump discharge pressure? Fire Engine […]
How do you calculate atmospheric stability?
How do you calculate atmospheric stability? Stability is determined by comparing the temperature of a rising or sinking air parcel to the environmental air temperature. Imagine the following: at some initial time, an air parcel has the same temperature and pressure as its environment. What is the relationship between atmospheric stability and temperature? A stable […]
How do you calculate the heat transfer coefficient of a heat exchanger?
How do you calculate the heat transfer coefficient of a heat exchanger? Composition = the overall heat transfer coefficient (W/(m2•K)) = the contact area for each fluid side (m2) (with and expressing either surface) = the thermal conductivity of the material (W/(m·K)) = the individual convection heat transfer coefficient for each fluid (W/(m2•K)) = the […]
Why a synchronous motor does not develop torque on starting?
Why a synchronous motor does not develop torque on starting? The stator carries windings connected to an AC supply to produce a rotating magnetic field.At synchronous speedthe rotor poles lock to the rotating magnetic field, beacause of the constant magnetic field in the rotor these cannot use induction windings for starting. Synchronous motors are inherently […]
What is sparse matrix in data structure with example?
Why Engineering is a great career?
Why Engineering is a great career? Employability. Creative thinkers, problem solvers, communicators, team players, it’s not surprising that engineers are some of the most sought after people for a diverse range of jobs. All kinds of businesses recognise engineers as people that are very well-educated and good at solving problems. Why did you choose engineering […]
