Asteam pipe for a 300-m-tall building receives superheated steam at 200 kpa at ground level. at the top floor the pressure is 125 kpa, and the heat loss in the pipe is 110 kj/kg. what should the inlet temperature be so that no water will condense inside the pipe?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
