Steam at 320°c flows in a stainless steel pipe (k =15 w/m "c) whose inner and outer diameters are 5 cm and 5.5 cm, respectively. the pipe is covered with 3-cm-thick glass wool insulation (k = 0.038 w/m - °c). heat is lost to the surroundings at 5°c by natural convection and radiation, with a combined natural convection and radiation heat transfer coefficient of 15 w/m2.°с. taking the heat transfer coefficient inside the pipe to be 80 w/m2.°c, determine the rate of heat loss from the steam per unit length of the pipe. also determine the temperature drops across the pipe shell and the insulation.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

no starving yourself won't it will make you lose more weight what you need to do is find out what foods make you gain weight like bread and meats with fat on
