stated that the friction material containing 10wt% micro-cellulose fibres showed comparable results with the commercial brake pads. The wear rate of the prepared by them material was found to be 3.7mg/m. COF value was determined to be 0.357. They also say that thermal stability of prepared ...
Fig. 11. Chips morphology at different drilling parameters: (a) f = 0.05 and v = 10; (b) f = 0.15 and v = 30; (c) f = 0.20 mm/rev and v = 40 m/mm. 3.4. Other drilling-induced damage Further non-destructive examinations on the samples were conducted with aid of X-ray compu...
In this technology, the material in filament form is fed through a heated nozzle up to melting and pushed in it by a motor, characterizing the deposition by means of extrusion, after which the material cools down and solidifies into the desired geometry. Since this process demands the use ...
It includes olive oil, which is only about 20% of the overall input volume, and two different waste matrices known as olive cake or olive pomace and OMW wastewater [29,30]. It is well known that the physicochemical characteristics of OMWs are changeable, depending on olive cultivars, ...
vegetable oil [HVO]) shifts the break-even point by 79%, 600%, and 64%, respectively. For these types of biodiesel, it is assumed that during combustion no CO2eq emissions are released [20]. Neglecting this assumption, the primary energy demand for the production of these three biofuels ...
According to the binary phase diagram for CaCl2—water system, the melting temperature of the 25 wt % CaCl2 solution is around −30 ◦C and thus the process takes place above the solidus line (assuming no dilution of the gelation bath). It can be assumed that, during the extrusion ...
[30] presented a study on the automatic prediction of tool life in turning operations. Aramesh et al. [31] investigated the remaining useful tool life under different values of cutting parameters in the turning of Ti-MMC using the actual tool wear value of the worn tool as the input data....
As of 2016, the hydel-to-thermal ratio became 30:65, thus indicating a dilemma that Pakistan's power sector mainly relies upon thermal power plants that feed on oil and gas [57–59]. As of 30 June 2016, Pakistan had a total of 25,374 MW power generation capacity, out of which 16...
The electricity consumption of the electric motor (25 W) for mixing methanol/catalyst for 30 min (0.5 h) at room temperature and drying WCO with a heater (500 W) for 30 min was obtained by multiplying the respective power consumption with the operating time. For the two-step esterification...
