The sticker inside the door of my car says that the tire pressure should be 32 psig (322 kpa) when the tire is cold. before a road trip, i fill the tire to this pressure on a cold morning when the temperature is 15 °c, and then head out towards las vegas. when i make a rest stop in barstow, it is now quite warm out, and the air in my tires has also warmed up from friction during the long drive. so, the air in the tires is now 60 °c. assuming my tires don't leak or expand (volume is constant), what is the expected tire pressure at this rest stop?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
