Question 42

what is specific weight of water

A) 1gm/cucm B) 9.81 KN/cum C) 9.81 Kg/cum D) 9.81gm/cucm

---

specific weight = density x acc due to gravity = 1000 kg/cum x 9.81 m/sqsec or N/kg = 9.81 x 1000 N/cum

Question 43

what is Relation between specific weight or weight density with mass density

A) specific weight = density/acceleration due to gravity B) specific weight = acceleration due to gravity/ density C) Specific weight = acceleration due to gravity x density D) specific weight = 1/density
