At steady state, a cycle develops a power output of 10 kW for heat addition at a rate of 10 kJ per cycle of operation from a source at 1500 K. Energy is rejected by heat transfer to cooling water at 300 K. Determine the minimum theoretical number of cycles required per minute.

Answer»

ong>ANSWER:

Number of cycle per minute = 75

explanation

Power output Wnet = 10 KW

Temperature of hot reservoir = 1500 K

Temperature of cold reservoir = 300 K

solution

we know that Efficiency is EXPRESS as

n = 1 -   

here  Tk is Temperature of hot reservoir and To is Temperature of cold reservoir

so put here value in equation 1 we get

n = 1- 300  ÷ 1500

n = 0.8

and Rate of heat input will be

Rate of heat input Qin = 10 × No. of CYCLES per sec

Rate of heat input Qin  = 10 n

n = Wnet ÷ 10 n    

put here value

0.8 = 10 ÷  10 n

solve it we get

n = 1.25

so here Number of cycle per second is = 1.25

Number of cycle per minute will be = 1.25 × 60

Number of energy cycle per minute = 75

Answer»

ong>ANSWER:

Copper is comparatively less reactive but reacts with REAGENTS like OXYGEN and water in atmosphere in a slow TIME. Also carbon dioxide helps in the reaction. As it is a metal, it will start corroding.

After some days, we will observe greenish layer on the surface of copper vessel due to the formation of copper carbonate. The required reaction is:

Copper when reacts with carbon dioxide, water and oxygen FORMS basic copper carbonate.

{ \boxed{ \rm{2Cu + CO_2 + O_2 + H_2O  \longrightarrow CuCO_3.Cu_(OH)_2}}}

The basic carbonate is a green coloured substance formed due time. Another example is the statue of liberty in New York, USA.

Answer»

ong>ANSWER:

Millions of people along the East Coast and in the Midwestern United States are under a heat watch this weekend as a MASSIVE heat wave bears down. This scorching July weekend follows what NOAA recently reported was the hottest June on record.

But before you reach for a plastic water bottle to keep hydrated, you might think twice about whether it too has been wilting under a hot sun.

“The hotter it gets, the more the stuff in plastic can MOVE into food or drinking water,” says Rolf Halden, director of the Center for Environmental Health Engineering at Arizona State University’s Biodesign Institute.

Most plastic items release a tiny amount of chemicals into the beverages or food they contain. As temperature and time increase, the chemical bonds in the plastic increasingly break down and chemicals are more likely to leach. ACCORDING to the FDA, the amounts of the chemicals are too minuscule to cause health problems, but scientists looking at the long-term effects of filling our lives with plastic say all those small doses could add up in a big...
