Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed.  Background information of Ethanol: Boiling Point = 78 0C Melting Point = -114 0C Starting Temperature = -120 0C After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely. After eight more minutes, it begins to boil. It boils for six minutes. Heat is added for two more minutes until ethanol reaches 80 0C. Label “melting” where this takes place. Label “vaporization” where this takes place. Label “phase change” where a phase change occurs. Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS. Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.

1.3 A mixture of two liquids of equal volume is made, the one has a relative density of 0,8 and the other a density of 980 kg/m³. What will the weight of 2 500 litres be? 1.4 1.5 1.6 15 1.7 [21830 N] A solid block of stone with a relative density 4 is broken down and crushed to an average size of 20 mm. If the stone originally had a volume of 50 m³, how many truck loads with a volume of 2 m³, will it take to transport the crushed stone if 25 of the crushed stone has a mass of 80 kg. Has the relative density changed? How much? Why? [32 truck loads] Use table 1.4.2 to determine the kinematic viscosity of crude oil with a density of 855 kg/ m³ at temperatures of 20°C and 100°C. [9,357 x 10-6 m²/s; 3,275 x 10-6 m²/s] Air is used in a sensitive gyroscope to keep the metal bearing surfaces apart. Will the friction losses in the bearing be higher, lower or the same if the temperature of the bearing increases? A widely used S.I. unit for kinematic viscosity is centi- stoke cSt. One stoke is…

ECO 5. AUTOMOTIVE. The power an engine produces is called horsepower. In mathematical terms, one horsepower is the power needed to move 550 pounds one foot in one second, or the power needed to move 33,000 pounds one foot in one minute. Power, in physics, is defined simply as the rate of doing work. The formula below gives the horsepower at 5,252 radians per second. https://philkotse.com/toyota-corona-ior-sale-in-baguio/1991-for-sale-in-aid7017151 625T 1313 where H is the horsepower and T is the torque a. Find the inverse of the model. b. If a taxi produces a horsepower of 200, what is the torque it generates? Solve here:

Kerosene has an API gravity of 42.5. What is the specific gravity of kerosene at 16°C? How does this compare with the value in Table 2.7? What is the energy density (MJ/L) of kerosene at 16°C? Use the data given in Table 2.7.

Pressurized eyes Our eyes need a certain amount of internal pressure in order to work properly, with the normal range being between 10 and 20 mm of mercury. The pressure is determined by a balance between the fluid entering and leaving the eye. If the pressure is above the normal level, damage may occur to the optic nerve where it leaves the eye, leading to a loss of the visual field termed glaucoma. Measurement of the pressure within the eye can be done by several different noninvasive types of instruments, all of which measure the slight deformation of the eyeball when a force is put on it. Some methods use a physical probe that makes contact with the front of the eye, applies a known force, and measures the deformation. One non-contact method uses a calibrated “puff” of air that is blown against the eye. The stagnation pressure resulting from the air blowing against the eyeball causes a slight deformation, the magnitude of which is correlated with the pressure within the eyeball.…

Question 7 The following formulas are commonly used by engineers to predict the lift and drag of an airfoil: where L and Dare the lift and drag forces, V is the airspeed, S is the wing span,  is the air density, and CL and CD are the lift and drag coefficients. Both CL and CD depend on α , the angle of attack, the angle between the relative air velocity and the airfoil’s chord line. Wind tunnel experiments for a particular airfoil have resulted in the following formulas.   where α is in degrees.
