Activity 1: conversion version whats your function? (10 pts.) directions: to complete this activity, answer each question, showing all work. one rainy afternoon you are making worms in dirt and realize youre missing the key ingredient, 0.5 lbm of gummy worms. off to the general store you go. upon arrival you are informed by the manager that the new scales use units of weight not mass, preposterous! you laugh because youll just use your smartphone converter app. you reach into your pocket only to realize you left your phone at home! gasp! no problem, youll just do the conversion in your head. quickly you convert 0.5 lbm to lbf to

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
