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 […]
What were machines powered by during the Industrial Revolution?
What were machines powered by during the Industrial Revolution? The steam engine helped to power the Industrial Revolution. Before steam power, most factories and mills were powered by water, wind, horse, or man. Water was a good source of power, but factories had to be located near a river. What tools were used in the […]
How do you finish PLA prints?
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 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 […]
Why is material selection important in the process of design?
Why is material selection important in the process of design? When it comes to material selection, design engineers you hire for your projects will more than likely have certain specific factors they look for as well. The fact is, material selection is very important because engineers have to plan for any potential consequences that certain […]
