A2m^3 rigid tank contains steam at 200°c, 25% of the tank's volume is filled with liquid, the rest is vapor. determine: a)-the pressure in the tank. b)-the quality of the mixture. c)-the density of the vapor d)-the density of the liquid. e)-the total mass of water (liquid and vapor) in the tank.

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.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
