The essence of many perfumes comes from the oils in the petals of fresh flowers, such as the rose, carnation, and orange blossom. However, fragrances are not limited to the petal, but can come from the leaves of lavender, peppermint, and geranium. Also, the oils of cinnamon and balsam are derived from bark, while the oils of cedar come from its wood. The fragrance of ginger and sassafras comes from roots, whereas that of orange, lemon, and nutmeg comes from fruits and seeds. Thus, there are many sources from which to derive fragrances for perfumes.
A certain population has a mean of 20 and a standard deviation of 8. Sample size 16 are taken for the purpose of sampling distribution. What is the expected value of all these sample means?
Suppose you mixed 1.65 grams of calcium chloride and 2.05 grams of sodium carbonate. What's the theoretical yield of the solid product?
A steady stream of air enters a horizontal compressor at the rate of 0.02 kg/s. The air temperature is 10o C at entry and 300o C at exit. The velocity of the air is 30 m/s at entry and 6 m/s at exit. During its passage through the compressor, the air experiences a heat loss of 105 kJ/kg of air. Calculate: (a) The change in kinetic energy per kg of air (b) The change in enthalpy per kg of air (c) The work done per kg of air (d) The power required to drive the compressor (e) The volume of air entering the compressor per second (f) The flow area of the entry pipe if the entry pressure is 1 bar Take R = 0.287 kJ/kgK and cp = 1.005 kJ/kgK
What are griots and how would you explain their role in society?
he engine mechanism shown in Fig. 8.38 has crank OB = 50 mm and length of connecting rod A B = 225 mm. The centre of gravity of the rod is at G which is 75 mm from B. The engine speed is 200r.p.m. For the position shown, in which OB is turned 45° from O A, Find 1. the velocity of G and the angular velocity of A B, and 2. the acceleration of G and angular acceleration of A B.
A shipment of five computers contains two that are defective. If a retailer receives three of these computers at random, list the elements of the sample space S using the letter D and N for detective and non-defective computers, respectively . To each sample point assign a value x of the random variable x representing the number of computers purchased by the retailer which is detective.
