SOLUTION MANUAL OF THERMODYNAMICS by Hipolito Sta. Maria Answered by: Engr. Naser A. Fernandez Published by: ‘I Think, Therefore I’m An Atheist’ Enterprises and Priority Development Fund (PDF) *This solution manual is an original work of Engr. Naser A. Fernandez. No part of this Manual may be reprinted, reproduced and distributed in any form or by any means without prior permission from him. j/k :-D Chapter 1 1. What is the mass in grams and the weight in dynes and in gram-force of 12 oz of salt? Local g is 9.65m/s2 1lb = 16oz Given: m= 12 oz g= 9.65 m/s2 = 965 cm/s2 Solution: (a) 12 oz x x = 340.2 g (b)Fg = mg/k = Fg = 334.80 gf (c) Fg = 334.80 gf x = 328324.97 dynes 2. A mass of 0.10 slug in space is subjected to an external vertical force of 4 lb. If the local gravity acceleration is g = 30.5 fps2 and if friction effects are neglected, determine the acceleration of the mass if the external vertical force is acting (a) upward (b) downward. Given: m= 0.10 slug x = 3.2174 lbm F= 4 lbf g= 30.5 ft/s
