VF=500+120t Donde VF es el valor futuro y t es el tiempo en años, determine: a) La tasa de interés simple. B) El tiempo transcurrido para que el inversionista reciba $600 de interés total. C) Cuál es la deuda inicial del quito año si el banco prestamista no ah recibidos intereses de mora y no cobrar intereses de mora. • Se obtenía un préstamo de $1,000 durante tres años y el capital banquero cobraba 5% de interés anual compuesto. La pregunta fue: ¿Cuánto es el monto que paga el prestatario al final de los tres años?

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
