Q2/ Acetylene enters to heat exchanger at ( 20°C) and ( 2 bar) gauge at a rate of ( 856 m'/min ) is heated at constant pressure to ( 97 C) by using a saturated steam at a gauge pressure of (2.5 bar). The steam condenses and leaves the heat exchanger as a liquid at ( 29°C). 1. Estimate the energy (KW) must be transferred to heat Acetylene from ( 20°C) to (97C)? 2. Determine the rate in ( m'/s ) must steam be to the heat exchanger. Assuming that all the energy transferred from the steam goes to heat the Acetylene.

Question
Q2/ Acetylene enters to heat exchanger at ( 20°C ) and ( 2 bar) gauge at a rate of ( 856 m'/min ) is heated at constant pressure to ( 97 C ) by using a saturated steam at a gauge pressure of (2.5 bar ). The steam condenses and leaves the heat exchanger as a liquid at ( 29'C). 1. Estimate the energy (KW) must be transferred to heat Acetylene from ( 20°C) to ( 97 C)? 2. Determine the rate in ( m'is) must steam be to the heat exchanger. Assuming that all the energy transferred from the steam goes to heat the Acetylene.
