Answer / sajil

ya deafnetly,anything less than atmosphere can be called as vacuum..

Answer / ankit negi

atm pressure is 1.013 kg/cm2 at sea lvel. at higher
altitudes atm pressure reduces,so a man at high altitude
will not be called in vacuum....

Answer / sudip bharati

vacuum is a negative pressure created by surrounding system
for their requirement, which is much or more less than the
atmospheric pressure. it is always measured with respect to
the surrounding atmospheric pressure either it is at hill
station or under the sea level.

Answer / renish

vacuum is always measured on sea/mercury level if atm
pressure is below some mmhg then its called vacuum

Answer / vaishtushar

Vacuum is space that is empty of matter.When the pressure exerting is much lesser than the atmospheric pressure then it is called vacuum.If it is slightly less than atmospheric pressure it is not called vacuum.fo ex at hill stationsthey are not living in vacuum.

Question 43 - In a non-dilute absorber, the inlet gas stream consists of 8 mol % carbon dioxide in nitrogen. By contact with room temperature water at atmospheric pressure, 65 % of the carbon dioxide from a gas stream has been removed. (a) Find the mole ratio of carbon dioxide and nitrogen gases at inlet and outlet gas streams. (b) The Henry’s Law provides y = 1640 x for carbon dioxide in water. Find the mole ratio when x = 0.0000427. Mole ratio is y / (1 - y) for y.

FOOD ENGINEERING - QUESTION 23.1 : (a) According to United States Department of Agriculture (USDA) (http://ndb.nal.usda.gov/ndb/search/list, accessed 12 August 2016), 100 g of potatoes generate 77 kcal of energy. For raw tomatoes, 111 g have 18 kcal of energy. Question : How much energy will one gain if 150 g of heated potatoes are eaten with 200 g of raw tomatoes? (b) If 1 Calorie = 1 food Calorie = 1 kilocalorie and 1000 calories = 1 food Calorie, then how many Calories are there in 9600 calories? (c) According to a food package of potato chips, 210 Calories are produced per serving size of 34 g. In actual experiment of food calorimetry lab, 1.75 g of potato chips, when burnt, will produce 9.6 Calories. For each serving size of potato chip, find the difference of Calories between the actual experimental value and the value stated on the food package. (d) The specific heat of water is c = 1 cal / (g.K) where cal is calorie, g is gram and K is Kelvin. Then what is the temperature rise of water, in degree Celsius, when 150 g of water is heated by 9600 calories of burning food?

Question 31 – For liquid benzene, the CP constants are : a = 129440, b = - 169.5, c = 0.64781. Reference temperature is 298 K. The temperature of benzene is 60 degree Celsius. Calculate the enthalpy of benzene by using the formula H = a (DT) + (b/2) (T^2 – TREF^2) + (c/3) (T^3 – TREF^3) where ^ is power, DT is temperature difference with TREF = 298 K. H is in J / kmol. DT = T – TREF.
